lulz, round.

That made more sense. I agree the ring seal will contain more of the "bang" than before. Maybe I will actually put this bottom end to the test.

But changing the cam profile will either let more air into the heads (lowering boost slightly), or it may even stay the same - with no other changes. You might also have more bleed off with a larger cam.
Not like I'm an expert, but I'll guess 760/695 as your number.

The cam lift is actually rather similar. It is going from a 224/236 115 to a 229/239 112. Lloyd was spot on with his cam spec before so while he says I might lose a bit down low, I should make it up considerably up top. After I informed him of the ring sealing problem, his comments were more definitive in gaining power all across the board.
