interchanging heads?

[80monteturbo]

i have a 1980 turbo monte carlo and i was goin to buy an extra set of heads to port and polish. i found a pair but i didnt know if all 3.8 heads are the same for the turbo charged engines. so if someone can help me out and let me know if i can put newer heads off a 3.8 engine on mine.

also if someone can tell me the stock valve size that comes in the turbo monte carlo 3.8

thanks

Any head from 79-87 RWD 3.8 will work with what you have for intake and exhaust manifolds. The latest casting for those years is the 8445 casting. 1.71intake 1.5 exhaust.
