Custom bore size Cometic head gaskets
The standard Bore opening size for Cometic MLS LS1/LS6 head gaskets is 3.910". The physical cylinder bore size by specification is 3.898". What is considered the safest minimum gasket opening size for the cylinder bore? I think I have heard of 3.903's. Can it even go tighter?
And yes, i realize chasing the tightest gasket opening to bore size is probably a waste of time, none the less, let's entertain this idea.
