Along with the loss of compression from going from a 60ish cc chamber to 64ccs, you have also lost perhaps a point of effective compression because you went from a cast iron head to aluminum head. If you want to stick with flat-tops, you would be better served with a cast-iron head, perhaps an EngineQuest Vor-Tec head with the manifold mating surface that matches your existing intake manifold.
