Default Re: EAB Heads & their Piston Reliefs - Is this right?

I'll check them, or see what my machine shop thinks at least, but these are EAB heads so I'm expecting this to be a problem in the piston area and to need relieving in the valve area with the Max-1 cam I'm using. I haven't been able to get a coherent depth reading in the valve pockets due to the slanted milling as well as the very rough texturing in the chamber.
