OEM Valve Seat Specs

How well do they flow in B and H motors, ie. how much room is there to improve?( how good is it from the factory)

Re: (Combustion Contraption)

What do you mean by 'never seen a B or H seat that couldn't be improved? Is there variance in the cut from the factory? How much can a street valve job be improved over oem?

Fwiw, here are the H22 specs which I'm sure you're aware of.
