yes they will i just put a set of double hump heads on my buddys 94 z 71 and they worked great.
As long as the 350 is older then a 1987, you will have no problems. They will bolt right on with no modifying.
no
the heads should fit as long as your not trying to put them on a big block
NO not even close.
No it will not, Totaley different.
no they will not
no
Yes.
a 350 is a small block those heads will fit on and Chevy SMALL block not a big block
No. Not without switching the cylinder heads. I think it was 89, Chevy came out with the 1st generation Vortec heads, which require a different intake.
No. The bore size is different between a 305 and 350. The 350 bore size is larger.
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
