Budget build on the cheap

Just my .02 on the thin head gskts: have seen many an undecked block and not resurfaced head leak, spray out ex side, or worse with theese. Ok if both block & heads have been resurfaced, but only both, not just the heads.
I tend to be a little more cautious and would go with the .039 gskts. Not really worth the expense and Marginal compr increase.
