I had to do some work on the 2nd OP side of the fixture to accommodate the Winfield heads since I have not machined any in this fixture before the two I am machining today. Here is the first one all machined.
The chambers CC at 120cc's including the 4" diameter piston relief that is .045 deep. Unless I am mistaken that is about 7.9:1 ratio with a cylinder bore of 3.975
