Is a thinner head gasket better?

Head gasket thickness will impact Compression Ratio. Changing gasket thickness can be used to fine-tune compression. However, the gasket’s thickness will also affect its ability to seal the combustion chamber and oil and coolant passages. For most engines, we recommend the OEM gasket thickness.

What does a thinner head gasket do?

Using a thinner head gasket brings head closer to deck, decreasing the area between the head and piston to increase CR. Since the pistons protrude from the cylinder on LS engines, using a head gasket less than . 040″ is really pushing it and rocking of the piston in the bore can cause piston to head contact.

What is the thinnest head gasket?

Registered. Around . 040 is about the thinnest composition gasket as far as I know, surface the heads if it’s that important.

Can you have too much compression?

Engine damage can be caused by compression pressures that are too high and can result in difficult starting and detonation. Is this true? The engine will not run as well as it should if the static compression pressure is too high or too low.

What do thicker head gaskets do?

A rule of thumb for automotive engines is that a 0.025-inch increase in head gasket thickness will lower compression about 0.5-points. For example, going from 10.0 down to 9.5-to-1 is a 0.5 decrease, which may be fine for eliminating detonation in a muscle-car running on 87-octane fuel.

How thick is a stock 350 head gasket?

What head gaskets to use?

– Solid copper construction, pre heat-treated. – Requires additional sealant for coolant (if liquid cooled) and oil passages. – Requires O-rings and receiver grooves for best combustion sealing. – Applications: Top Fuel, Blown Alcohol, Nitrous, and all Boosted Gas race engines with O-rings (and receiver grooves) in block or heads.
