Head work by Pro1RacingHeads!

[ktmpegger]

Had my RMZ450 head done by Pro1RacingHeads out of Phoenix. Machines his own non-beryllium valve seats out of Mold Star 90 stock and valve guides from a nickle-bronze alloy. He doesn't cut the valve seat but uses a Haas machine to profile them. He does porting and verifies his work with a flow bench.

Haven't noticed much change on the bottom end but did not loose anything. Head starts to shine mid-range and above!

Great videos.
Thanks for the info.


FWIW, I used to work at a place in Orange county with a 5 axis machining center. We could bring in stock and have it machined, if there was no other work. Made some great disk brake rotor shark fins, skid plates.
