I have a SIRII head (p30) what would those cams be comparable to and if i put just the intake cam from a CTR should i see or feel gains?? Or i'am i better off useing both CTR cams.

 

If you change your cams don't forget to upgrade your valve springs and retainer. You will notice a gain with ctr cams.

 

i have upgraded my valve train with omni flat-valves,omni dual springs, and manley titanium retainers,and a 3 angle valve job. so shes all set ,just wondered if i could get away with changing out the intake side with a CTR cam and leave the stock exhaust cam..
