Yes. The smaller valves will increase the low-end torque and limit the top-end horsepower potential, and the smaller combustion chambers will likely increase the compression ratio a bit.

Can 305 heads fit on a 350?

What will 350 heads do on a 305?

Will the top end of a 305 fit on a 350?
intake no, heads yes.
Will 1995 Chevy 350 heads fit on a 1995 Chevy 305?
No. The bore size is different between a 305 and 350. The 350 bore size is larger.
What small block Chevy heads can you use on a305 4bbl Chevy motor?
305 heads of course, 350 heads will fit for sure and possibly 400. obviously no big block heads will fit. a 305 with 400 heads gets you a little over 352. 350 with 400 heads is a 383. add and divide
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.
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.
Will regular old style 305 heads work on a newer vortec 305 block?
The heads will fit the block, but the vortec intake manifold will not bolt to the old style heads.
Can 1977 305 heads fit on a 350 block. and what other suff from a 305 fit to a 350 block?
heads will bolt on but will not work. the combustion chamber is too small resultingin too much compression.most anything else (brackets,exhaust accessories etc.)will work
Will heads off a 305 or 283 fit a 350 Chevy?
As long as the 350 is older then a 1987, you will have no problems. They will bolt right on with no modifying.
Will 305 vortec heads fit on a 350?
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.
