Lots of people use the thicker headgaskets. It's not so much that they cause knock all the time, it's just that you might not be able to reach MBT at lower boost levels (sub 15psi).
Yes, the head is straight. Heck, if you want, I'll get a price for shipping and you can just pay for that, then once you examine the head, pay me the rest. I'm not tryin' to rip ya'.
