302 cylinder head question

Hey guys needing some opinions on cylinder heads , I just bought a 93 short bed with a 302 in it, the truck either has a blown head gasket or a cracked head , so the heads are getting replaced the question is should I just put stock F150 heads on it, but I also thought about putting GT40 or GT40P heads on the engine , would the GT heads be a gain?

GT40's flow about 20% better than the stock E7TEs and GTP heads about 30% better.

Conanski, can a GT40 or GTP heads be put on a stock 302 F150 engine with no mods to the fuel system or the intake or computer ?

You should not need to make any changes other then the question of the exhaust and plug angle on the GT40P heads. New plug wires may be needed if you are using anything other then stock cast iron manifolds.
