360 build recommendations please...

No way I'd ditch the heads. K>I>S>S... Toss a bigger cam in it and run it. The XE274 will need dual springs, new retainers, and locks. Going to smaller valve heads simply isnt worth it, and in a light car with a decent stall and gearing (I'd go 3.55 and kep the tires stock diameter) the car will run way into the 12s. With some traction aids and careful suspension tuning, low 12s. I dont think 11s are realistic without some bigger mods. But in any case, now way I'd run a 2.02 valve with that package. Different strokes for different folks...lol
