So I'm pondering HKS 272's and am wondering about the longterm effect on the valvetrain and eventually the motor. I know a lot of you guys are going to say "you make more power, you're going to sacrifice engine life" ...or something to that effect. But I like to drive my car everyday, and realize that making power has it's negative effects, but I don't want anything detrimental, as in say extreme wear on the valvetrain. I maintain my car like crazy and would like to be able to have good power and still use it everyday. So just wondering if anyone has experienced bad results from cams, the HKS's more specifically. THANKS!

 

I have had the HKS 272's for 50K miles, now I have the HKS 280's for 10K miles, still STOCK head, no problem!! I have had my problems in the past, but there is NOT enough room to explain it all out!! The only part I have NOT had an issue with, was the cams and the head.
