If both engines have a carburetor on them, THEN NO. They will interchange.

Will the top end of a 305 fit on a 350?
intake no, heads yes.
Will a block from a 350 5.7 work with heads from a 305 5.0 and 305 intake 1998 If the 350 is not a vortec?
No it Has a different bolt pattern because of the engine size
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.
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.
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 can you add horsepower to a 1986 caprice with a 305?
carb, cam, intake, headers, heads, msd igntion, or a 350
Will Chevy 5.0 heads and intake fit a 5.7 short block Chevy engine?
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.
Will 305 heads make more horsepower on a 350 1990ish motor with carb conversion?
No. 305's have small valves due to the 305's small bore. Large valve heads can't be used on the 305 because the valves will hit the cylinder block. 350 heads breathe MUCH better than 305 heads. Stick with the 350 heads.
Are tbi 305 and 350 heads the same?
no
Can 305 heads fit on a 350?
Yes
Can you run a Chevy 350 cam in a Chevy 305 with stock 305 heads?
Yes, but running a 350 cam with 305 heads is not effective,you need to run 350 heads as well. In order to benefit from a 350 cam you need something to flow that extra fuel and air, so using 350 heads along side of the 350 cam will be the cheapest and best choice. HAVE FUN!! A 350 head can physically bolt onto a 305 block. However, 350 heads can have the valves extend into the cylinder and contact the cylinder wall (even with the smaller 305 cam). The 350 cam in the 305 with stock heads will work. You wont want to use 350 heads you will lose compression due to the largers combustion chambers.
Will 350 heads on a 305?
Not a good idea. 350 heads will lower compression to 7 to 1 or less.
