You know about the 516 heads, right?
Yes, closed chamber - and have the smaller 1.6" exhaust valve, along with smaller exhaust ports in need of someI should rephrase that they are most likely the stock 516 heads, I actually haven't checked into them that much. Should be closed chamber, probably soft valve seats unless the previous owner upgraded them when it was rebuilt a while back. With the head gaskets on it, flat top pistons, and only 130psi cranking I can't figure those heads should be much of an issue for the time being? I'm using some really cold plugs and pulling a ton of timing as well.
