 ONLY THE ALUMINUM HEAD HAS 8 (DUAL) PLUG CAPABILITY.

BOTH the Iron and Aluminum have the exhaust and intake wall surrounds enlarged as much as possible to fit "Best Brand "B" gasket. 

Head is designed to run 1.732" (+ -) intakes and up to 1.732" (+ -) exhaust valves.

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

Head could be ordered without a fly-cut for a small fee.

 the combustion chambers are 140 cc's.

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

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

 All Lion III and IV heads are mass produced and machined for 140 cc with 4 plugs on the driver's side.

Machine work for 4 more plugs (aluminum ONLY) and higher compression is additional and extra.

How many do you want?  $50 deposit guarantees you get one.

 ALUMINUM AND IRON

 Cast Iron III Version

Dyno'd Out Of The Box At: 92.96 HP, @ 3200 rpm @ 6.50:1 CR with 171.91 ft# torque @2000 rpm

 AND

Dyno'd Milled with Modified Chambers At:  115.41 HP, @ 3500 rpm @ 7.25:1 CR with 183 ft # Torque @ 1700 rpm.

As tested by Piranio's Antique Automotive. See the dyno sheets linked here: (www.modelaparts.net/dynosheets.htm/lionstk.htm)

Note: Piranio's cc measurements differ from ours.

He measures our advertised 7:1cr head to be a 6:5cr.

Both are probably correct due to slightly different measuring methods.

*In the past we have had buyers order a head and then take a pass when ready to ship. So, the small non-refundable $50 deposit is to guarantee that you get head from the next production run and it is non-refundable to cover our costs if you need to back out.

 

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!

 

Lion chambers shown above

IGNITION CAP & WIRE SYSTEMS AVAILABLE BUT NOT INCLUDED

 

 

   

LION SPEED HEAD

 

 

HOT-HOT-HOT!

 

 

High compression for serious drivers.

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

 

 
 
 

CNC Machined

Combustion chambers are precision machined to exacting size for an excellent gasket fit.  The special CNC computer program gently carves out the combustion chamber and mills in a fly-cut above the piston.

 

We recommend ONLY the "BEST" brand of Model B Head composition gaskets  for use with the high compression  Lion III and IV.

 

We stock the "BEST" line of Gaskets & Rebuild sets.

 
 
     

 

 

 

 
 

These caps have special plug wire boot terminals instead of old style pins.

Precision made of high quality.

* Cloth wire sets are covered with a UV plastic coating to protect from water and oil. They will keep their good looks for years.

 

Ignition fires with common 14mm, 3/4" reach, flat seat with a ring gasket, spark plugs, which are centered above the piston.

You will need longer wires!

We offer special made "winged" distributor cap, cover, rotor and "cloth" wire sets* available for $89+SH

Fit only Model A & B distributors.

Wires for other brands of ignitions can be ordered.

 

The Lion is King!

 
 ALUMINUM
  The new 356-T6 aluminum Lion head - like all (100%) aluminum heads - is susceptible to electrolysis. A zinc bar must be placed in the water flow to act as the sacrificial element. I know of no coatings that will stop the electrolysis. Proper grounding of the engine will improve the situation and I have heard that a water soluble oil mixed into the water system will help. Stay away from copper head gaskets as this will aggravate the situation. With care and preventative maintenance the aluminum head will last for many years of enjoyment.
