YES they will bolt right on it with no problems.
If this engine is to be used on the street, it would be advisable to add the steam holes to the heads. You can use the gasket as a template to mark where the holes go.
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
350 heads will bolt to the 400 block. They will need to be drilled for the "steam ports" in the 400 block.
The heads will fit the block, but the vortec intake manifold will not bolt to the old style heads.
Yes, they should fit ok. 305 heads should bump up the compression a little.
They dont make a 350 big block.The big block starts at 400. Wrong! 400 is still a smallblock. Big block Chevys start at 396, but does not include the 400, which the heads/crank and starter/etc. fit on the 350/305 etc.
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
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
all external bolt on parts will work. heads, intake, dist, cam, pan, timing chain, oil pump etc. should all work as well. most internal parts will not work though. such as pistons crank rods and block. The 305 crank will fit the 350, but will need to be balanced. i would not use the 305 heads due to small compression chambers.
No, Not even close, Totally different designs.
No, no, no. Two totally different motors.
Yes, they will fit on the block. The larger combustion chambers of the 307 heads will probably reduce the compression ratio by a fair amount, reducing power output.
