Yes, but I don't know why you would want to use them on a 350. 305's are limited as far as valve size is concerned because their small bore causes clearance problems with the large valve heads... Larger valves will actually hit the block on a 305. Just about ANY 350 head is better than ANY 305 heads.

Will regular 305 heads fit a 350 Vortec engine?
No 305 heads bolt up different then 350 heads If they are 305 vortec they will bolt up. However they do not have the same flow. The 305 vortec head has smaller runners, smaller valves and does not have the same heart shape combustion chamber. Now if you meant the older 305 heads onto a 350 vortce then no they will not. The vortec uses raised runners and the ports will not match. On top of it all the 5.7 vortec has more flow then any other production head. Placing a 305 head in its place would be going backwards.
