Not without A LOT of modification.

Answeryea they will fit but you will have to switch over to the newer style valve covers because of different bolt patterns AnswerYes they'll fit, but like answer #1 some modifications. Two intake bolts are angled different, than the others. You'll also have to change valve covers. I have a set of LT1 heads with 202 160 valves, ported and polished and seven sixteen screw in studs and a hv1000 brodix intake and its fast. So it will work. also the heads have to be drilled for the water to flow through the intake. three holes alltogether(2holes drilled in between center exhaust ports below spark plugs on each head.

Not mentioned above is the fact that the LT1 heads have to be welded in 4 places or water will flow into the intake valley on a gen 1 block. GMPP has a carb manifold with provisions for a distributor for a LT1 that I used on my LT1 head on Gen 1 conversion. I also drilled and tapped the front of the heads for water return.
