Yes. And max compression is dictated by spec limits. Adding stroke does not increase compression except for the additional displacement added to the mix.

Yes. There are comp. calculators all over the 'net. One can run the numbers and see if you think it's worth the extra effort.
To me, the indexing and smaller pin size are at least equal in value.

BTW, thank you to to Dwight for what you do for racers....Appreciated by 98% of them ,and called names by those who are Left.

Gasket thickness (A) and deck (B) can vary, but total of A+B has to same as or greater than NHRA spec. .000 deck and .040 gasket = -005 deck and .035 gasket or +005 deck and.045 gasket. Give yourself a few extra thousandth to the good side so you can be fearless in tear down.
