I just realized that your heads are 781's. These, along with 049's, are the best of the best iron oval port heads that Chevy ever cast up for a BBC. Using the right recipe, it'll be hard NOT to make 500 hp with them.........
Look around for a shop with a good reputation who can install 2.19" intake and 1.88" exhaust valves in your heads (after measuring the ones that are in there now. Somebody could have already changed 'em out).Last edited by techinspector1; 01-07-2020 at 02:00 PM.
