Need help figuring out my dynamic compression.

What piston? If it has valve reliefs/dome it will change the compression.

I assume this is the hughes cam you are running? Hughes Engines
That is the cam. Piston is a diamond flat top piston. The specs on the piston says it has a valve relief of 6.8cc but we measured it at 6.9cc. There generic guidelines also said it was 2.070 on the intake which was actually closer to 2.015. We didn't have to cut them for my 2.080 valves.
