4.00" bore head gasket options?

Not quite BigKid, its somewhat the opposite. You'd have a tighter quench which increases combustion efficiency and fights off detonation. Personally, I'd rather have that .043 gasket than a .060 for that reason.

Quench is the reason I was looking for a thinner gasket in the first place.
I have just read that the overbore of the gasket may hurt as much as the reduced thickness helps.

I am probablly going to go with the Cometic 4.00"/.040 gaskets. The are a little pricy but will be worth it if/when I pull the heads off again. Plus the quench on those will be much mo nicer.
