There might be, but hard to say when you have large overlap cams bleeding compression out the exh valve.
When you test, make sure you run the test the same way. Like warm the engine up, and test with the carb at WOT. Make sure the battery doesnt run down so you have the same cranking power. This can effect the numbers, or if the engine cools etc.
Look at each cylinder and they should be with in 5% of all others.
I like my race engine in the 225-250 lbs + range.

I healthy street engine should approach 200 psi. But many factors come in play here
