I tried to talk to a tech at comp cams (after waiting 30 minutes) and needed some info on valve overlap for a hyd roller. To make a long story short, I could have got more info from the Gal at Mc Donalds about cams. (they have great coffee.) If the tech is that ignorant imagine the guy putting the grind on the cam. "What Lobe".
I don't buy from them.
