Evo 10 - Cometic - 4B11 88mm Head Gasket 0.50"

Cometic 4B11 MLS Head Gasket, 88mm Bore, 0.50" Thicker Section. Evo X

Gasket thickness quietly sets your static compression ratio. Adding thickness opens up the combustion chamber a fraction and pulls compression down, which is exactly what a heavily boosted 4B11 wants because it buys margin on timing and knock. The cost is a slightly less eager engine when it is off boost, so the choice comes down to what the car is built to do rather than which number is bigger.
