Is a .100 flycut about right? A friend and I are installing a Comp Cam XER 242/248 .610/.615 111lsa. AFR heads milled .034, 2.02 valves, using .040 Cometic gaskets. Does flycutting about .100 seem about right for the intakes? Also what about the exhaust valves, they are the 1.60's. what should they be flycut? Thanks

We've taken measurements till we are blue in the face, We were gonna start with .080 but the Isky tool collar was fkd up, so we cut a little deeper than we were going to initially. We have the cam in with the degree wheel installed.WE are waiting to get the heads back. We thought we would start cutting before we got the heads back to save a little time. A number of shops told us at least .080 minimum so we figured .100 would be OK. Any thoughts?
I would just be guessing, which does you no good. I would rather do it once and go a little deeper than having to do it all over again or worse yet, smack a valve. I'm sure someone here has a similar setup and can give you some ideas.
