So I got 4 sets of heads that I can use on the 350 i'm rebuilding on my 86' Camaro. Im running a Edelbrock 600 cfm, a .488/.510 lift cam, weiand excellarator intake.. i think thats about for what matters. oh and Ill be running a 50 shot of nitrous at the track.So I could use some input on which heads I should run on the car that would give me decent flow and some bottom end power. I have a set of 333882's which ive read about and them and they either say their boat anchors or they're not bad heads.I have a set of 462624's I beleive. which most of what ive read people say is that they're just the same as the 882's. I have a set of 350 swirl port heads that were on the car when I bought it. and last but not least I have a set of 305 heads off one of my old cars.(not high output). Ive heard putting a set of 305 heads on a 350 makes a mean little motor off the line but Id like to get some opnions before I do anything. Whichever set i decide im putting on the car will be getting some new seals and guides and will also have a set of roller rockers on them. Hope to get some good imput.
