My question is does the valve angle have have any bearing on the external surface of the head that the header flange will mount to?
Obviously if it does have bearing than it would change the way LS headers fit different heads. I don't think it does have any bearing ( I think the angle is referrring to the angle the valves are oriented to the combustion chamber), i just want to be sure.
Thanks,

the headers will bolt up. My ETP LS2 heads are 11 degree but still have the same angle of exhaust port versus block. Yes, they are speaking of valve angle, port angle at the head isn't the same although the port size and shape certainly are. I don't think I would run a 1.75" header on an LS7 though, but it should work as long as it covers the port (no exhaust leaks).
