KB 107 pistons

I do intend to balance it. I was hoping there would be a stock bore piston that I can use that would give me a point bump in compression. I really don't want to mill the heads unless it's the only option. I intend to get a valve job done and some mild porting to increase flow.

Ideally I would like to come in around 9.5 to 1.

When I used KB107's in my 360 with X heads (66 cc chambers) the compression came out to about 9.65 to 1 with no block milling. The heads were cut .010 to clean them up. When I was looking for pistons the SP's were in the low 9's on compression using the same figures
