Re: Headers and dual pattern cams? (FERL 73)
FERL 73 the longer duration of camshaft the more the scavenging effect from headers helps cylinder blowdown. Single pattern or dual pattern isn't as important as exhaust duration. I recall reading short single pattern cams <270 duration are not as responsive to headers as longer durations. A short duration cam won't allow much exhaust savanging anyways. The longer duration cams require more time to allow exhaust blowdown. :yesnod:
More important I think is a tight lobe centerline and for a 350 chevy 108 is tops. No one sells a C.A.R.B. legal 108 cl cam and if I didn't live California I'd have bought an Isky. :yesnod:

YES!
buy the best quality headers you can! Try Thorley first and then anything else later.
