ka-t headgasket question

hey guys. got a quick question. this is mostly for the guys who are running over 14psi. heres my setup

built forged bottom 9:1
bc 264 cams
bc oversize valves
all arp hardware. im running the old arp headstuds(the 1.9 saturn ones)
t3/04e @ 15psi
hks 740cc


so i blew my first head gasket. was a felpro. took the head off and everything is fine. nothing is warped. i was at the strip and i just got my bee r a few weeks ago. testing out the 2 step... anyway #4 cylinder started burning coolant after my third pass. car has around 10,000 on the new motor. coolant was NOT in the oil.

the gasket had two small holes between cylinder 2&3 and by #4 as well.

so my question is..im going with a felpro again.is there anything i can do to prevent this from happening again? a buddy had the same thing happen to his KA-T(built with t28) after a few thousand. he said that instead of just hand tightening the studs in like it says. he used an Allen key and tightened them down pretty good before putting the head back on. haven't had a problem since. also i saw that on arp's new stud kit for the KA it says you can use locktight but you must torque the head down before it sets. soo any tips...

btw i did post this in the FAQ section but apparently no one is home anymore
