PtoV clearance with this custom cam? I am going to be ordering a custom grind. My problem is I have asked tech support at a couple of vendors and they don't seem to know jack! I've got GMPP ported LS6 heads which are milled .055 and have the stock valve sizes in them. I also have the thicker 03' head gaskets on the car.
I want a max effort camshaft, so I need as big a cam as will safely fit without flycutting.
I was thinking 230/230 .575 .575 110 lsa
please any experiences/ feedback would be greatly apreciated.

There are just too many variables for anyone to guess to see if it is going to work or not. You should ALWAYS check for clearance.
Good luck,

there has to be some rough formula that you can use to get a ball park number. For instance, let say you start out with .600 lift to work with , minus the milling of the heads .055. This leaves you .545 right? The confusion (for me) starts when you try to factor duration into the equation. There has to be someone on this board that has real world experience with heads milled .055 and a similar cam. where are you?

lets say you took one of the sponsors biggest cams that you knew would work on stock heads without flycutting. then subtract .055 lift for the heads being milled. Then you ordered a custom cam with the same duration and LSA but with .055 less lift. That should work shouldn't it?
