I've got a forged 408 arp main studs all TSP internals with wiseco pistons rings gapped for NA via instructions with the pistons thinking .0020 and .0022 but I'm running stock head bolts. How big of a shot would be safe with stock head bolts. Also if bolts are replaced with studs how much can I go with the ring gap I have. I'm considering a 200-250 shot if the ring gap is ok.

I've personally sprayed 250hp on stock head bolts but this also was with a bone stock untouched LS1 motor. Being a forged 408 might be a little different because you're already making some good power N/A. As far as the shot i'd probably stick to around a 150-200hp shot and call it a day.

That ring gap I wouldn't go over 200
