Need more info like why are you changing head gaskets, and what was in there previously
Changing them cause I just aquired this car. Its been sitting for a while from previous owner, and is leaking from head gaskets slightly. And just to give it a good once over since its winter here now. Also going to be changing fuel pump gasket too cause its leaking but thats pretty straight forward.

I havent pulled the heads yet to see what they got on it now.
 
Need tear it down and see what the piston stick out is, measure piston to valve clearance. A typical FelPro .040 type head gasket should be fine but there might be some reason a thicker one might be needed. Or maybe a thinner and add some compression.
