Need to know the year.
YES, If you have center dump exhaust manifolds you will want to make sure that they will bolt up to the 350 heads. You did not say what year heads you are going to use. BUT more the likely they will bolt up.
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.
305 heads work on a 350 engine
2 bolt or 4 bolt main?? is it stock??
bolt them on their the same
It should bolt up without changing the heads.
350 heads will bolt to the 400 block. They will need to be drilled for the "steam ports" in the 400 block.
Only you can determine what is best.
Advertised Horsepower is--165HP @ 3800 RPMs.
Stock 350 horsepower. With all the mods you can achieve 1,250 horsepower. (But you run the risk of blowing heads.)
I had one with 10:1 compression that was making close to 350 hp with decent heads.
YES. The heads will bolt right on.
