I'm currently in the process of building a forged block and have a couple of questions What's max safe boost on 20vt block ? Which headgasket ? Can't seem to find arp head studs? Is there a alternative ?

Just watch out if your boring the block out the thinner the cylinder walls the more likely to cracking which we have seen on the more boost happier coupes outside of the UK.

The only time you should worry that is if you are doing the 2.4 stroker pistons 82.5mm for 2346cc not 83.00mm for 2446cc,because it greatly expanded the block lose strength in the walls of water... So at .5 you are fine nothing to worrie about .
