Thanks Bry593. Yes, the different machining does not make me feel too good about these heads. Those Summit once look really nice and affordable, but I've never replaced heads, although I had never done valve seals either till a week ago, so maybe I could do it. Can you change the heads without doing any changes to the pistons? just remove the heads and install the new ones? I wonder how my stock 327 would do with those.

As I already have springs coming in, I think I will install them, install the new intake, carb, and HEI distributor and see how she runs and if it's still not happy I may just go ahead and get those heads.

Thanks.
