Message	head bolts, and pushing combustion out, thus blowing the gaskets, and causing all kinds of carnage. When removing the headbolts they would almost be finger tight from being stretched so badly. I believe the 2jz crowd has ran into the same thing, and now run arp L19 grade stock sized bolts. Russell looked into having those made, but they were extremely expensive, and probably not enough support from the z32 crowd to support them. For now this is the most cost effective solution. whatever complications/setbacks I run into getting these studs to work may bring. it still beats having this happen. 9.46@142 1.37 60ft
