Road Warrior  1.900

     The Road warrior package from Atwood Performance take the Twin-Cam cylinder heads to a whole new higher level of performance.

     If you are looking to maximize the torque and horsepower available from your stock Twin-Cam heads, these are the ones for you. Big airflow equals big torque and horsepower. In order to make the big power that todays performance enthusiasts demand, the needed supply of airflow must be increased. As the name implies, on the Road Warrior 1.900 cylinder head, you will find the intake valve has been increased to 1.900". This is just what the cylinder head needs to obtain those big flow numbers needed to supply that 100+ horsepower producing engine. Atwood Performance has found that a 1.900" intake valve and a 1.570" exhaust valve provides a perfect balance of intake to exhaust flow. Exhaust flow averages near a perfect 80% with this combination and precise port work.

     Nothing but the best parts go into these heads and they have been assembled with the idea of extreme punishment on a daily basis, while maintaining exacting tolerances.
