Description

.010" Thin Head Gasket for 70mm Tillotson Engines.

Add Compression without machining by adding a thin head gasket to your 212 Tillotson, Predator, or Clone Engine. Simply remove your engine's cylinder head, remove your thick head gasket and replace it with the new .010 thin head gasket.


Example: Typical Hemi Predator

.045" Head Gasket

70mm Bore x 55mm Stroke with 23cc Head, 0.025" Deck Height, 0.045" Thick Head Gasket = 8.14:1 Compression Ratio

.010 Head Gasket

70mm Bore x 55mm Stroke with 23cc Head, 0.025" Deck Height, 0.045" Thick Head Gasket = 9.07:1 Compression Ratio

That's a .93 gain in compression. Results may vary on cylinder head combustion chamber, deck height, or changes in bore and stroke.

Be aware of how quickly you can gain compression with small changes.


Built Example

70mm Bore x 55mm Stroke with 18cc EC Big Valve Head, 0" Deck Height, 0.010" Thick Head Gasket = 12.19:1 Compression Ratio

Warning! A higher Compression Ratio will require higher octane fuels and will be more difficult to pull start.
