360 heads on 318

valiant mike, the bottom end is not together yet, im just shopping for parts at this point and wanna have a game plan before i start spending money.

bjr racing, i have read and followed the 349ci on the cheap thread for a while and while that sounds very appetizing, im actually considering it, however the streetability factor is very important to me. like i said ive heard a lot about the 302 heads, but im not sure how much id need to spend on them for them to make as good as or better flow numbers than the 360 heads
