I probably have to take my 4.600 bore BB chevy out to 4.625. What head gaskets are you guys using. I have some Fel-Pro 1057 that are 4.630 bore but on the notes on the package they do not recommend for the 4.625 bore size. Any thoughts please. Thanks

Cometic can make you any size bore and thickness that you want. I get custom made sizes all the time.

If you go to ebay and type in 4.640 you'll see people who are selling head gaskets at that diameter....

I just put a set of 1077-1's ( Fel Pro) on one this week. It had 1077's on it but I noticed the pistons kissing the heads so I used the .010 thicker vesion. -1 being .010 thicker than 1077
