Yes, all 305-327-350 small-block Chevys share the same bore, except the sb 400. Make sure you check (2) things - 1 - The piston-valve clearence - especially if you're using high-compression pistons, a high-lift cam, 2.02" valves, or a very small small head chamber size. 2 - Note that you may increase the compression ration to a value that requires you to run high-octane gas or retard the timing to a point that defeats the purpose of the upgrade.

Do the 305 vortec and 350 vortec have the same heads?
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.
How do you swap a 95 305 Chevy for a 350 Chevy engine?
the block & heads are the same you just have to pull the 305 out & put the 350 back in
Will 1979 305 heads fit a 1988 350 vortex block?
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.
Can you put a carb 350 intake on a 305 tbi engine?
yes it will fit, 262-400ci chevy smallblock manifolds are interchangeable.
Can you put 305 heads on a 350 bored 30 over?
Yes. Beware that 305 heads usually have smaller combustion chambers than a 350, which would increase the compression ratio, possibly requiring premium fuel to avoid pinging.
I have a 1993 chevy 350 that came out of a van. it has 2 barrel heads with a throatle body. i want to change it to a carburter.ihave a 1984 305 4 barrel heads .will heads work on 1993 350?
Chevy heads are not thought of as 2 barrel or 4 barrel like Ford Cleveland heads. Your 350 has heads with bigger valves than a 305. The 305 heads might have smaller combustion chambers, which would raise your compression ratio. Before pulling the trigger on this swap, I'd suggest you contact Summit or Jeg's and ask them about interchangeability of the intake. It's possible that a new intake is all you need to put the carb on your 350.
What will i have to do to put 1990 350 heads on a 1985 350 block?
The 85 intake manifold won't work with the 90 heads, so you will need to purchase an aftermarket intake if you want to use a carburetor or use a 87 to 95 intake if you want to change over to TBI.
Will 305 cylinder heads cause overheating on 350?
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.
Can you put 1969 camel heads in 1990 tbi 350 truck?
Yes you can. But you will need to use a different intake manifold,one ment for a early model small block engine
Im lookin at a 305 block with 350 heads minor mechine work done to them a mild cam and intake and the block was just redone would it b worth putting in your truck now it has a 350 in it?
You sure about that being a 305 with 350 heads. If so, skip it. The compression would be terrible.....Extremely low. Most 305 engines use somewhere around 58 cc heads. If I remember correctly. 350 uses 72-76. Of course there are many that are lower cc... especially the hi-po heads. Doubtful that the ones on there would be that small. If you have something stating the cc of the heads from the machine shop that would give you a place to start. One of the things guys have done is just the other way around. 305 heads with a lot of work done to them put on a 350 to up the compression. Unless you are planning on a supercharger or blower you won't want that 305.
Can you put your Chevy 350 1983 intake and heads on a 1989 t.b.i Chevy 350 block will it work?
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.
Can you put vortec heads on a 1990 5.7 tbi motor?
Yes direct bolt on.
