Advancing Cam Question

Is that true "as told" or true "as measured"?
Measured it meself. Don’t have the numbers handy.
.030 KB190’s, 915 heads I don’t remember the cc’s right now.
I do remember using a thicker hg than planned, cuz I had to pull the heads when I discovered some dirt, and I already had some thicker ones for when I put them back.
Actually, I’ll post the numbers later, I need to refresh me ol memory anyway.
