Well i'm going to replace the HG on my Supra. I'm going to use ARP Studs and a MHG. I'm just wondering why is there different size HG's? I was looking and there were 4 options. 1.2mm (Stock?) 1.4mm 2.0mm (Most people use?) and even a 3.0mm (why so big?). I have a 7M-GTE im going to machine the head to perfection and do it right with ARP Studs i jsut dont know what size to use? Oh after my rebuild i intend on running more boost and probly installing a 57 or 60-1 Trim Rebuild CT26.

Forgot something whats the difference between Stopper and bead Hgs?
