P51 Cylinder Heads - Precedent Ford
Kaase did not shrink in modesty when spec'ing the cam profile for this engine. The custom COMP solid roller 'shaft features 256/262 degrees duration at 0.050, and delivers 0.761/0.743-inch lift with the COMP Pro Magnum 1.73:1 ratio rockers. Longer-than-stock pushrods are required with both the P51 and Super Cobra Jet (SCJ) heads.
