They will fit, but the engine won't perform very efficiently. Also, 283's didn't have accessory bolt holes on the ends.
yes all sbc manifolds will fit, when you get to cyl heads then you will have trouble since most aftermarket are for 350 bore which is larger
yes just get head gaskets for the 350 not the 327
the heads should fit as long as your not trying to put them on a big block
yes
yes you sure can.
No. The 350 has bigger valves. While you CAN put the 305 heads on the 350, (I can't imagine why you would actually want to) you can NOT put the 350 heads on the 305. Because of the 305's small bore, the valves on the 350 heads will hit the cylinder block.
Yes. they didnt change the 350 block very much.
the block & heads are the same you just have to pull the 305 out & put the 350 back in
LT1 gen 2 to LS1 gen 3 no
yeah, but it might blow a head gasket, i wouldn't chance it
Yes they will, But you will have to drill the 4 center bolt holes out in the 88 intake to make it bolt up to the 305 heads. I don't no why anyone would want to put 305 heads on a 350 engine, The 350 will never run like it did before.
They can if the heads are cracked ,are the intake manifold gaskets were put on wrong when thay were installed. The heads themselves if thay are good heads will not cause overheating. You cannot put the head gaskets on wrong on a small block Chevy engine.
