Question about oem head gasket

[leftynridge]

I'm getting ready to take my 88 turbo to the dyno and wanted to find out what type of power that a oem head gasket can hold? It has ARP head studs and is torqued down to 85 ft. lbs. When I got the car it was already done.

My current set up is a 60-1 ct, spearco replica ic, rc 550's, walbro fp, aero fpr, map-ecu, 3 in. exhaust, spec stage 3 clutch.

Was the block and head resurfaced? If so id say 500hp, as long as your tune is good. If not it kind of up in the air. Id say 350hp can be done safely.

Uh oh

I don't believe that it was, but the guy I got it from said that he had the head looked at and was told that it was ok. But it is hard telling what to believe.
