Comp was no help. Thanks in advance.

My best advice is find a racer / machine shop with a Cam Doctor and have them spin it! There won't be any guessing then. I check my new cams just to be sure. Or get your dial indicator and degree wheel out ,stick it in a block with a rotating assembly in it , grab a cup of coffee and start measuring.
