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. Pricing is for pair of heads.
Bare Street/Strip Port Job: Send us your bare heads. We port and polish the intake and exhaust runners enlarging them increasing airflow and smoothing out airflow disturbances. The combustion chambers are smoothed and polished giving better airflow around the valve head and better combustion flow. Cam journals are polished. We return your heads for you to do the machine work.
Ported, Machined, Sprung: Street/Strip 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 camshafts (or you can purchase Kelford uprades from us) We measure and set the valve lash to your camshafts and install your scissor gears on the camshafts which usually requires modification because of the larger lobes. Heads ready to bolt on Short Block.
