Head Gasket
Im swapping heads on my 302 and put a set of ported E7's on it. They have been milled 10 thousandths. Do they make a gasket thick enough to compensate to keep the compression ratio stock?

Don't worry about compression it won't change enough to affect anything, but you will need 10thou shims for the rockers to get factory preload on the lifters.

I found these two kits at summit racing. Either one would work if I combined the two shim sizes right? They would equal 9 thousandths (.090) but I figure thats close enough.

10 thou may not be enough to worry about in terms of rocker preload, but thicker head gaskets are available to take up the slack in any event, even Summit has various options.
