 CAST IRON SOLD OUT UNTIL LATE SUMMER

 


 A Neat Piece Of Info:

Four (4) of these heads (that I know of) are destined for  land speed trails in 2012 at Bonneville  

 Results: THE LION SPEED HEAD  POWERED DENNIS PIRANIO'S MODEL A COUPE, AT BONNEVILLE 2012 TO A NEW WORLD RECORD FOR A MODEL A FORD, COUPE BODY, CHASSIS AND A MODEL A BLOCK - THE LION IS THE MOST POWERFUL EVER MADE . . .SO FAR

 Now Hear this

The results of further dyno testing by Dennis Piranio, (www.modelaparts.net/dynosheets.htm/lionstk.htm) who announced today (1-10-2013), that "4 spark plugs on the left (driver's side) produce more horse power than with 4 plugs over the valves". This test was conducted with state of the art testing equipment with a Model A test engine. The cylinder head was a cast iron Lion Speed Head dual plug. The only change was moving the spark plug wires from over-the-valves to the left side. This resulted in 1.5 HP increase at 2500 rpm.  We recommend, for street use, timing to be set at 28 degree advance. We are recommending 26 degrees only in racing environments where idle is not an issue and rpms over 3000 are used.

LION IV ALUMINUM: The Lion IV aluminum 6.5:1 CR head has been tested and it has the same horse power/torque as the iron Lion Head III. It has the same power characteristics as the iron Lion . . .much to my amazement. I suspected that the aluminum job would come up short but it turned out to a screamer too.

We do not have results with all 8 plugs firing at this time.

There has been a continual buzz (mostly from California boys) that plug setups (driver's side) like the Lion are detrimental to performance. We have known for a long time that this was bogus. Bill Stipe was the first to dyno the Lion about 10 years and that test also found 1.5 HP increase with the side plugs. This latest test conclusively proves that assumption to be dead wrong and keeps the Lion Speed Head on top of the pack as one of the most powerful cylinder heads ever made for the Model A or Model B engine.

 

 Always use a Model B head gasket with Lion Speed Heads

Special features of both the IRON And ALUMINUM cylinder heads

NEW -Head's "new" chamber design will accept 1.732" dia. intakes (recommended) and 1.732" exhaust valves (usually stock 1.50" are the best choice).

The heads have 1/16" fly-cut over the piston. This is insurance against piston pop up, which is too prevalent these days.

 The combustion chambers are 145 (+-) cc's.

The CR is approx 6.5:1 CR at stock bore and stroke with zero piston pop up and our gasket.

Total possible valve lift of 0.600" (+ -), without special machine work. 

 All Lion Speed heads are mass produced and machined for 145 cc with 4 plugs on the driver's side.

Extra thick deck, cast walls and chambers, which can be machined for varying dimensions and/or higher/lower compression ratio required by the owner.

GASKET FITSCAMBERS COMPLETELY MACHINED!

A direct bolt on.  The Lion III increases horse power and torque,  the engine runs remarkably smoother, saves fuel, is easier to tune, runs cooler and really looks GOOD!

Chamber volume (cc's) tightly controlled by computer aided milling machine. All chamber are equal in volume (+- 2 ccs).

 

NOT INCLUDED: Electronic Ignition kit  -  Special Winged body, cap, wires kit  -  Spark plugs  -  Head gasket - each are available as options.

Spark plugs: Not Included - 14mm, 3/4" reach (threads), with ring gasket, flat seat.

Recommend AC DELCO R44XLS as a good starting point.


To Protect your future needs

We cast and machine these FANTASTIC cylinder heads once or twice a year. The schedule is based on many factors that are constantly in motion. If this is the Cylinder Head for you then I would recommend purchasing one (or two) whenever they become available. Seldom, if ever, have we had a stack of them on the shelf. They are good investments and are easily resold through auction sites and swap meets.


IRON  Dyno'd "Out Of The Box"  At:  92.96 HP , @ 3200 rpm @ 6.5:1 CR with 171.91 ft# torque @2000 rpm.*

 AND

Milled by owner to 7.25 CR, removing the flycut, was dyno'd at   115.41 HP  @ 3500 rpm, with 183 ft # Torque @ 1700 rpm.*

ADDITIONAL MILL WORK AND ABOUT 8.25 CR, WITH MANY (MANY) EXTRAS, DEVELOPED AN ASTOUNDING 190+ HP

 

 These kind of factual, tested and guaranteed numbers, for a flathead Banger, are unheard of in the industry!

As tested by Piranio's Antique Automotive. See the dyno sheets linked here:

 (www.modelaparts.net/dynosheets.htm/lionstk.htm)

*The tested Model A Ford engine ran with 1 dual throat carburetor/manifold, header, electronic ignition, and "touring cam".


 

 
 

ACCORDING TO THOSE THAT OWN A LION SPEED HEAD,

"THIS HEAD MAY BE THE MOST POWERFUL AND EFFICIENT

HIGH COMPRESSION HEAD FOR FORD MODEL A's & B's EVER MADE". . . .

TIME WILL TELL!

After years of research we have settled on, and strongly recommend, 55 lbs of torque and the Model B sized, steel composition, head gasket manufactured in the USA by the BEST GASKET COMPANY. Our testing and the experience of our customers confirms this over and over again.

These fit up to .090" overbore and are successful up to 7.5:1 CR and are a one (1) time use gasket. Always carry a spare.

These are a special mixture of arimid carbon fiber sandwiched under high pressure over a steel core with steel fire rings around each combustion chamber. Each surface is coated with a space age polymer that actually melts and seals the capillary surface features of both the head and the block. No sealer is required.

For long term success in fighting gasket blow-outs and annoying water seepage you really can't do better. . . IF the head and block are truly flat.

 Torque Down

These gaskets require three (3) initial torque downs. It crushes and relaxes with heat until fully seated. We recommend 55 pounds of torque*. Use no sealer. Use fresh water until gasket seat is finalized. Torque to the "Model A Ford torque sequence" slowly and evenly to 55 lbs. Run Engine to normal hot and allow to cool over night. Follow this sequence two (2) more times (3 days total). A hassle? Perhaps, but a world class seal is the result.

 

What to expect: After the first torque there may be a small amount of coolant seepage. Clean it up. You will find the torque setting to have dropped. Re-torque in sequence to 55 lbs.  There should be little to no seepage and less torque lbs lost after the second torque. After the third re-torque there should be no coolant seepage and the numbers should stay at 55 lbs. Re-check after 300 miles.

* 55 pounds of head nut torque is optimal. Torque values over 55 lbs, on a Model A or B Ford engine, causes the cylinder bores to begin warping and begin to pull up metal around the studs. Once this damage is done, and held for a time, it can not be fully reversed without a cylinder hone job and deck surface re-mill. The stud threads can hold more torque if they are in good condition but it is not advised. More engines weep coolant and blow gaskets at 65 lbs than at 55 lbs

 BECAUSE OF  WARPAGE TO THE DECK AND CYLINDER WALLS.

 HOWEVER, we can not warrantee these gaskets. They are excellent, but we can not control how they are installed, torqued, maintained or used.

What causes gasket failure?

Heat, pressure, dirt, uneven surfaces and poor torque sequence . . . High torque situations like chugging slowly up a steep hill in third gear, when, in your heart, you know you should be in second gear. Or in drag racing when sudden high pressures and tremendous heat are created.

OVER TIGHTENING BEYOND 55 LBS, UNLESS THE BLOCK WAS BORED TO HIGHER TORQUE LBS WITH A TORQUE PLATE IN PLACE AT MACHINE WORK TIME.

The heat created can reach the point of melting the gasket steel or copper edges. Pressure pushes on the softened gasket,  eventually it burns and blows through.

Avoid racing and down shift to keep your rpm over 1000 and under 3000 rpm.  Racers must understand the consequences and be prepared.
