Hello all!
I'd like to know if any '66 GTO head can be made an A.I.R. head just by unplugging the end caps, and how easy is that on a very old, long-time plugged head? Or if it's worth doing even? I have incorrect heads on it now, and it is the original AIR setup (no A/C) which dictates a timing change but obviously does little for emissions, per the CO warnings and no cat converter. I am sure running the AIR pump with plugs in the heads would kill it fast, and I kind of want to keep it stock. 389, Carter AFB w/4 spd. Any thoughts out there?
