CHP shows the compression at 9.2:1 with the 58cc heads and a 4.030 bore. However, I don't think the block is going to need to be bored. I think we'll be able to just do a hone on it but Eric will have Speed-O-Motive confirm that when he drops off the block. I'm kind of hoping it doesn't need the bore so that the cylinder walls will be thicker for a little more strength.
