[QUOTE="phil a, post: 16884481, member: 45445"] The safest option from my viewpoint is using ARP head studs at 85-90ftlbs I’d use the 2000s given your goals As much of a pain in the ass as it’d be, I’d use that initial torque, get it fired/heat cycled, then pull both cam covers and recheck torque on all the fasteners Aluminum heads and now aluminum block - more expansion and once that HG crushes with a heat cycle, the studs may not have the same clamp load as they did initially Pulling the cam covers is a huge pain in the ass, blower has to come off too, etc but if it was mine and I’d spent $$$ on parts/assembly, that’s the route I’d go I think less concern if one piece (block/heads) was iron like stock…but with mid-20lb boost goals might be worth considering [/QUOTE]
