No problem calculating the actual CR if we know the chamber CC. Without that, it's just guesswork.

I understand the calculations... but I thought someone had already been there and done that, given the relatively stock nature of the parts involved. Surely there wouldn't be that much deviation (one head to the next), WRT comb chamber volume? I was just looking for an estimate, after all. :)

See Paul's explanation for why hitting the valves is no prob...

I also understand canted valves versus vertical valves, but you CAN run the valves into the pistons if you take enough metal off the mating surface of the head; it doesn't matter at what angle the valves happen to be canted. I was simply after the number (head height) at which that might happen. If it is, in practical terms with this combination of parts, unlikely... Great!
