Integral Cams
The stage 1L - 2L performance cams are designed to work with the stock valve springs to 7000 RPM. The stage 3 - 4 road race cams require performance valve springs.
All of the profiles are available on new Chilled Cast Iron Billets. When ordering please specify if you want a solid core billet (that uses external oiling) or a rifle drilled billet (that uses internal oiling). Also, you can specify a different lobe separation angle for no extra charge.
