no you cannot they are not interchangeable the 89 heads are fuel injected heads and the 79 are carb heads and will not interchange
all small Chevy heads are 65 ft lbsin a circular motion from the center out
You would also have to change the intake manifold, with the heads. I feel compelled to advise you, you are going backwards in technology, thus less performance, and mileage. The newer heads flow better. However, I understand the need to get on the road cheaply, so if you use the older intake, yeah, you could do it.
NO. The intire fuel system, Heads, Intake and valve train / cam and lifters are DIFFERENT.
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.
Yes it will work the block bolt patteren never changes from 350 to 350. You might run into a problem with a intake manifold not going on though unless you have it too for the heads you want to use.
1979 267 / 350 engine ! Danny Coleman
It should bolt up without changing the heads.
If both engines have a carburetor on them, THEN NO. They will interchange.
Yes. they didnt change the 350 block very much.
Should bolt right up... that motor didn't change for 40 years.
Yes as long as you change both heads.
No. The 350 has bigger valves. While you CAN put the 305 heads on the 350, (I can't imagine why you would actually want to) you can NOT put the 350 heads on the 305. Because of the 305's small bore, the valves on the 350 heads will hit the cylinder block.
