Re: Head Work
What about extude hone for the intake, head, and exhust.? I
would not go big valves unless you want to lose low end power for
high end speed. Somthing about cyclinder head velocities or
whatever... I think extrude hone will be the best thing to do to
the head and manifolds for a few reasons. One being that the
prosess removes material from the entire runner not just the ends
where you can get a grinder. It smooths the material in a flow
pattern much like water erodes a river bank in a natural efecient
manner. So more POWER and more MPG all at the same time. But leave
the turbo alone. Again the high end thing.
