No. Not without switching the cylinder heads. I think it was 89, Chevy came out with the 1st generation Vortec heads, which require a different intake.
nothing. but the intake will be diff.
No not even close.
In the cylinder heads.
Yes, however, they both take different intake manifolds, so you will have to transfer the intake, as well.
Depending on years that you are swapping around....yes. The 305 heads will raise the compression of the 350 considerably. However, the intake valves are a lot smaller than the 350.
Yes you can but you will need to modify the bolt holes in the intake manifold. The TBI intake 4 center bolts, 2 on each side will not line up with the heads. Must drill them out just a little.
The 5.7 heads will work if they have the smaller 184 intake valves . Or you will have to bore the block over to get the 194 ,200,or 202 intake valves to fit into the cylinder if not it will lock it up when the valve opens and hits the edge of the block
Remove carburator then intake manifold then cylinder heads
It depends on whether or not the intake ports match on the cylinder heads. You can get that info from one of parts exchange guides you may find online.
Yes the oil ports are the same.
replace the intake gasket set
