Default Quick question on afr heads.

I ordered some afr 225 heads that are large bore heads. in the instruction sheet for the heads it says to use a minum of 4.135 bore size for the head gasket. this makes no sense to me because my motor is a 370ci and the bore is a 4.030 ... can someone explain this to me? thanks

It might be the combustion chamber width or the flare at the top of the sleeve. Ask Tony, sure he can answer this one.
