I have HKS 272/272 on otherwise stock head. Not to agressive imo, but they are more agressive than the BC 272/272 I was running. There is a huge thread somewhere on the fourms that dyno tested several different cams. Just do alot of research. There is also a very imformational video I used to help me with my instillation.
