Re: 139 hp 302 ford help
For longevity of the block it might be best to start with a deck clearance of .010 to .015 if gaskets are available to bring the number to .048. If is easier to skim cut the block in the future than to shorten the rods or de-stroke the crank to get to the legal numbers.

Re: 139 hp 302 ford help
The early 302 blocks (68-72) deck height are about .020 lower than the 73 and up 302 blocks so with a early block you're close to 0 deck height and with a later block you're about .020 in the hole. Brian Seaberg 627

Cometic has always made us whatever thickness gaskets we needed
to get deck and gasket height whatever we have need to be legal.
