1uzTech Custom Cylinder Head porting dramatically increases air flow and makes more power. Whether your Naturally Aspirated or Boosted, in a serious effort to make power you want the best cylinder head flow possible. We offer a few different cylinder head package options.
Bare RACE Port Job: Send us your bare heads. We start by removing the valve guides. We then port and polish the intake and exhaust runners, drastically enlarging them, straighten airflow plaths and smooth out airflow disturbances. The combustion chambers are ported and contoured around the valve heads to increase flow, smoothed and polished giving better combustion burn and detonation protection. Cam journals are polished for more clearance. New valve guides are installed. We return your heads for you to have the rest of the machine work done locally.
Ported, Machined, Sprung: RACE port job. Head sealing surface machined, valve seats cut and lapped, valves reconditioned, new valve seals, and valve springs installed. Head stud holes enlarged for 11mm studs if needed.
Full Package: Everything Above plus send us your cams (or you can purchase them from us) We set the valve lash and install your scissor gears on the camshafts which usually requires modification because of the larger lobes. Heads ready to bolt on Short Block.
FULL RACE Upgrade: Machine head for ARP Pressed Chromoly T Washer for 11mm head stud. (ARP T Washer Included)
