I have wade grind cams in my 2T-G. They are a different number obiously. Mine are ment to be 305.5 degrees duration, and seam to be very close to that when I dial them in on my motor. I will be doing this again (dialing in cams) in the next week.
If I can have a look at your cams, I think I can tell you everything you need to know. We have to measure some things. More compression is good, but not needed to make the motor run. We can measure valve lift, piston clearance should not be an issue, unless you make a mistake installing them. Set up valve clearances about the same as the factory book says.
