The GTS has problems with detonation same heads (But with extra cooling on the exhaust port )....And yes One customer in Australia tried the 85-86 USA short block with S-4 heads it was NOT HAPPY neither was he ! Just the thought of taking out the head studs from the 85-86 block would deter me from wanting to try this, I would only use the 87 > head bolts. You could get away with the high compression by running race fuel but that gets expensive as well.
