LION SPEED HEAD III CAST IRON Castings HAVE BEEN Ordered - We Are In Production PROGRESS REPORT 2-1-2012: All cast iron and aluminum heads have arrived at the machine shop. Each iron head has been electrostaticly painted black. The engineers have reviewed my changes in chamber design and will make a sample chamber for cc-ing and QC. Look for photo here soon. I have ordered a few extras. . . why you guys wait until the end ??? The Machine Shop will schedule after chamber design is nailed. Let's estimate late February + - . Thanks for waiting!!
6.5:1 CR (140cc), 4 Plugs on Driver's Side
LSH-III: IRON $549.00 - 4 PLUGS ONLY THOSE WITH A $50 DEPOSIT** ARE GUARANTEED A HEAD. DEMAND IS HIGH - WE SELDOM HAVE STOCK "ON THE SHELF" AFTER DELIVERY. DELIVERY + - LATE FEBRUARY (2012) SOSS member's please take a 10% discount
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. 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 140 (+-) 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 140 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. 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 powerful 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) when ever 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.* 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".

Prototype image with OPTIONAL 8 spark plugs The Aluminum Dual Plug** Our newest lighter weight Speed Head features dual plug capability** The head is delivered with four or (optional**) eight plugs for $89.00 extra. The left side angled Spark Plugs are the default position, which dyno at highest HP. (Dual plugs require special ignition system with 2 coils.. - NOT INCLUDED) The combustion chambers are 140 (+-) cc's with 4 plugs. The CR is approx 6.5:1 CR at stock bore and stroke with zero piston pop up. Head can be machined/decked at your end for up to 10:1 CR Note: Not shown in this photo is the new Water Access tapped & plugged hole on top right rear corner. This hole is threaded to 1/2" NPT and can be used for water temperature sensor or a water heater connection. ** The second set of spark plug holes MUST be pre-ordered ($89.00) before machine work begins. ** Spark plug hole machining instructions, for your machine shop, are included. For HEAD GASKETS See below Wire Kits for Model A or B or "Zipper" distributors. (Will not fit other distributors)
Our cap kits have special plug terminals instead of old style pins. Precision made of high quality. * Water proof yellow cloth wire sets are covered with a UV plastic coating to protect from water and oil. They keep their good looks for years. $89.00 per kit Head Gaskets For The Lion Speed Head I, II, III, IV $45.00 ea. + $15.50 shipping (1-3 gaskets) Buy 2 or 3 at one time and save on shipping SOSS member's please take a 10% discount 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. 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. 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. Racers understand the consequences and be prepared. ** DEPOSIT INFORMATION Deposit amounts are specified above in the copy. Deposits are NOT refundable AFTER the castings have been ordered.
