What bore size would you run a 2.08 valve at? I would think that would be getting close to the point of needing to mill the intake side of the chamber to match the head gasket bore to see the full benefit.
My head fixture on my flowbench is 4.010 and tapped and locate my heads with studs so I can’t cheat and move it over from the wall and I’ve hit 325cfm with a 2.08 valve.
