Twin Cam cylinder head rework

 

Level 1                                                $ 359.95 Level 2                                                $ 659.95   Level 1: Port and blend bowl area and smooth radius into combustion chamber, clean up combustion chamber. Our port work is designed to help flow and velocity of intake and exhaust as well as provide a better burn rate inside the combustion chamber. Twin cam heads require more work in the intake port area as the port tapers in to the valve reducing flow. We open up the taper to get better flow as well as blending into the combustion chamber.   Level 2: We combine all the porting on the level 1 heads with larger intake and exhaust valves and upgrade valve springs to accomodate high lift cams. We use a flow bench to perfect our head flow and have some secrets to tailor your heads to you performance package and riding style.
