Anyone tried them?
I think at this point it’s almost all trial and error with the XX. I will let you guys know next week when I get a baseline dyno with my first cam how we think they worked.I'm with Bo on this one, If the head had poor exhaust flow then larger valves would be helpful. The larger exhaust valve may hurt the torque curve since flow isn't an issue.
No one has tried it yet though, Sometimes things that aren't supposed to work do lol
