Might help to know what you're starting with. Can we assume an LS1 between '98 and '02?
Gaskets - use the ones for LS1 bore size. Thickness depends upon the static CR you're shooting for. .041" compressed usually work well on a stock displacement and chamber size LS1.
Bolts - I assume you mean head bolts. Use the ones for the year of your block like it says in the listing.
