best set is the hedman 79071 2x or 4x4 or the hedman 79080 for 2x only.

I prefer the 79071 on a 2x as the starter R&R with out moving header. and when the oil filter drops off it does not soak the tubes.

I beg the diff on a stock 318 not getting any boost in performance Just adding headers and duels.

that's what I do first. headers and free flow duels. advance the timing and adjust carb.

that was the best thing for the old LA BBD 2v carbed 318 IMHO.

the stock TBI roller cams respond well to a small 4v and headers as well once you ditch the electronics stock Ign.

then grab a stock 5.9 roller cam and toss it in with a carb/headers.

have it reground on the cheap or like all my lopo 200,000 mile JY engines go with the Hughes whiplash cam flat tappet or roller cam.

once I recurved the dist on the 440 whiplash it sounds like a pro-stock but drives like a 68 new Yorker around town.

my little pre-mag 318 whiplash roller was awesome with the NV4500 5 speed 3.55 gears in my stepside.
gone back to a CRT/TF-2 727 non lock up with a stock 10" high stall TC installed a e-body 8 3/4 with a 3.23 and is still awesome daily driving.

LMK you need parts. got plenty to trick one out.
