if it would fit on there it probably wouldn't run the greatest. putting 305 heads on a 265 make the combustion chamber bigger, which causes a loss in compression... i wouldn't do it if i was you
305 heads work on a 350 engine
Yes, they will work. but you wont gain power because the little 305 isn't putting out enough flow to keep up with the heads
Heads off a 454 engine will not fit a 305 engine A 454 is a big block and a 305 is a small block. Even if they did fit it would probably run poorly due to low compression because the combustion chambers on the the 454 heads are larger than the ones on the 305 heads
No it Has a different bolt pattern because of the engine size
yes
Yes they will fit right on there with no machine work are problems.
Because of the 305's small bore, you're pretty limited. Large valve heads (2.02/1.60) won't work on a 305 because the valves will hit the block itself. If it's an older 305, your best bet would be the old power pack 283 heads. They flow better than the older 305 heads. Now, if it's a vortec engine, you probably won't do much better than what it had stock. If you are really trying to go fast, the best thing you can do is junk the 305 and replace it with a 350 or a 327.
The heads will fit the block, but the vortec intake manifold will not bolt to the old style heads.
Yes, and well.

take them to a machine shop
In the cylinder heads.
