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.
