When you do your torque checks, please check the intake bolts. My 72 lemans has an Edlebrock intake and has blown 2 intake gasket sets. I replaced them again, and re-check the torque after every heat cycle the first three times, and find most of them loose again. I have used thread sealant, and even blue loc-tite on them. After the first three times I re-torque, and check them every 2 heat cycles. Then I find about half of them loose. After another couple checks I find a couple loose, then finally none of them loose. Just my Pontiac 350 engine and maybe something is a miss. I just don't want you to have another problem you could avoid. Just do a "nut and bolt" check on everything on the car for awhile. Just saying.
