4.1" bore= .030 over?

bcmbcmbcm · Jun 1, 2009

Hey folks,
I came into a new set of Fel Pro permatorque MLS head gaskets specified for 4.1 " bore. Is this appropriate for .030" over?

Thanks!

stock bore is 4.000 and .030 would be 4.030. 4.100 is .100 over stock bore

I believe all of their SBF gaskets except loc-wire gaskets are a 4.100" bore. I have 1011-2's with a stock bore and they're a 4.100" gasket.

i was wrong

i was wrong on the gaskets they say the 4.100 is for a stock rebuild

i was going off this Cometic Gasket, Inc.

looks like 4.1" gasket for any bore from stock to .040" over?

That is the impression I am getting....any thoughts?

The 4.100" bore is appropiate for a motor that is 4.00"-4.08", I use them all the time...
