Like I've posted before...Comp started that crap so the guys who do the dot to dot thing would get the ICL where they wanted it, without bushings, offset keys or multiple key way timing sets.
There is ZERO reason not to degree a cam and the tools to do it are cheap. The process of degreeing a cam is relatively simple. And no one should invest in a timing set that doesn't have multiple key ways in it.
Degree the cam. Every time. And then you KNOW, for a fact where the cam is.
I hope the OP has seen the weight of advice for degreeing the cam and he does it. Then he can be sure the cam is where it should be.
