Head Porting Question

95talonracer · 11-09-2006

I have found that the comp cams in my interest are the 272 style and run like 370 or so brand new. Is this a good choice and what are the power increases in these? Also will the crowler springs and titanium retainers be fine? I heard they are good to like 10,000 safe. I have some SS valves and revised lifters with new guides. Anything else ill need here?

No you will be fine. I would also tend to agree with John that the "old school hks 272" and the new fp cams are great cams for the 4g63 head.
