I use the valves that I will run and put tester springs on then use the dial indicator to measure from 10* before to 10* after TDC so I can see if I can move the cam around for the installed.. I do every degree and measure to when it touches the piston and I do both the intake and exhaust... thats just how I do it
thats what i did the last time i was diving into this. i have to check my notes.but the 10* btc and atdc is really the answer to my question. if thats adequate to use to pic a cam
