If you have to run stock castings, they are pretty good. With some work they can be really good.

e7te late model car/truck castings are only about 2 cc difference than the earlier 69/70 windsor heads but with smaller valves but the exhaust ports are less restrictive. I would put bigger valves in the newer castings easier to find.

Yeah, E7 castings are good too, as well as GT40 and GT40p, though the p castings have some header fitment issues due to spark plug locations.
