zz4
alright i have this 350 ZZ4 engine, and i have a 350 in a 72 chevy truck, i was wondering if i can throw a carberated intake on the zz4 if it would bolt up to the stock L31 heads, i was also wondering if my 186 camelhump heads would bolt up to the engine if the water holes are the same, also the zz4 has a roller cam setup in it and i have a high-perf cam in a n other engine but the cam is not a roller, can i use the roller lifters and the other cam or no.

If you have the ZZ4, why change the heads? The ZZ4 heads are better than either of the two you mention.
And NO, you cannot use roller lifters in a conventional cam.
