You'll lift a head or take out main bearings from main cap twist

You can datalog coolant pressure to see when the head lifts. I'm going to do this next year

Been using LS9's like so many others. They work really well for so many and are probably the best choice within reason. I am contemplating trying the ones TSP sells since my heads are off now, but cant seem to justify the cost since the LS9's have worked well.

I have never seen those...pretty sweet. I feel like unless your running an LSX platform, you have other issues before the gasket. Maybe with the aged ARP head studs that are like $650 and these gaskets and good ARP main studs in a 5.3 iron block, you could run huge boost and break the factory block (not shortblock, I said block) record before having to go LSX.

I have to disagree. Seen may guys lift heads before having any other issues.
