You will need to have the heads for the 305 bored out to the same size as the 350.
I disagree: you can use the 305 heads on the 350 block but you will increase compression as the 305 heads have a smaller combustion chamber. The critical dimension is valve clearance. If compression ratio is a critical consideration, different pistons may be available which will bring the combustion chamber back to size. the 305 is from the 3.671 inch bore family. The 350 is from the 4.00 inch bore family. All small block heads have the same bolt pattern.

Yes they will, but 305 heads have a smaller combustion chamber so it may raise your compression ratio.
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.
