I have a 1976 TRW performance parts catalog, it show that the L2295F stock bore has a 13.10 effective dome volume, with a .022 thick head gasket and a deck clearance of .020 with a 85.40 CC combustion chamber you should have 11.90 to 1 comp. ratio. you can use the dome volume to plug into one of the on line calculator with different deck hieghts and combustion chamber volumes to get the calculated compression ratio of what you have listed. I have used the exact same numbers on Wallaces and KB sites and ended up with different compression ratio
