So are you saying a 4 angle valve job is the only thing to do for performance?

I'm saying when sticking .100+ larger valves in them that without the 4th lower 70 or 75... the bowl/throat will be smaller than stock in relation to the seat angle...and flow terrible. Even just as or more crucial is the deshroud for .100-.300 numbers.
Not only is that cut opening the bowl and transitioning it better... it's also helping the short turn by moving it more upright vertical ridding the over hang.
