Yeah i think they had a pretty lose tolerance on that 9.6" deck height though. Mine also had a taller deck on the driver's side. Ended up with 9.575" after they were cleaned up and evened out, and a 0.013" positive deck height with KB167s.
Did you have issues with intake manifold fitment With the block decked that far?
Yeah but I have few different manifolds I can put on so I managed to find one to fit (portosonic) but the heads have been milled a bit to get from memory about 58 to 60 cc from the 302 closed chamber heads.
You have to measure it to really know where you stand.
