Re: junk 305 or not
416s are decent heads for a 305. I wouldn't want them on 350... 327? Maybe...! With some judicious port work and larger valves, this head can make good power.
We try to steer people away from "pinning" heads anymore. It "works", but if you have any trouble with the stud down the road, you're in big trouble. If you're adding heavy valve springs, that usually means a bigger cam. That calls for "screw-in" studs and pushrod guideplates. Any good machine shop can install them for less than $200. "Pinning" is something "left over" from the 1960s. Jim
