The blowing out straight across was a coincidence. possibilities: warped head or block, block threads not clean giving an improper torque reading, bolts bottoming out, defective gasket, improper torque sequence/amt, bolt threads dirty/nicked giving improper torque reading (as above not enough clamping force but the torque wrench shows enough), block/head surfaces not clean (debris)

Stump how much quench clearance did you have (before the milling took care of it)

It has ARP studs and was torqued 30,60,then 90 ft. lbs. the block was surfaced .010" and the heads checked good.
Sounds good there. Thanks Stumpy for answering my Q

I believe it was right at .025 which was too tight.
If you ran your motor with that little clearence the piston would have been tagging the head hard. Quinch has nothing to do with your head gasket problem. By milling the top off the piston you would be lowering your compression and that is what may be saving your gasket but that is a crutch.I run .038 piston to head and that is pushing the limit, most engine builders like to see .040 piston to head. I use cometic gaskets and so does every body racing in NASCAR with no problems. A cometic gasket is made of stainless steel so if you hurt a cometic gasket the block and head would have been torched.
