Good luck

I was afraid of what you mentioned, so I did a full degree on the cam, checking everything i.e. Intake opening and closing values along with exhaust and compared those numbers to th cam card and they are on.
This is why I'm so frustrated at this point.
I am thinking about removing the heads, install an old iron set and try it on my buddies run on stand at this point. The only thing Howard's suggested s that the cam is really small and with my compression (static) being 190 lbs yet doing a compression calf it should be 10.0 to 1 and static compression #s closer to 170 to 180. So they suggest a larger duration cam to lower the static pressures to the 170 to 180 which should help.
