If your running hooker comps 2455. They will hit. That’s what I run. Hedman (try getting that thru spellcheck) fit well also. My next stop is Lemons, when The money tree ripens.

ooo 409.. cool.. I always though they were neat, but my Dad, who was a Chevy guy back when they were new, was never impressed.. he called them "Glorified School Bus Engines". He was a small block guy back then, with latest tricked out 283 in his 60 Chev.

I used to have a '69 SS396 Chevelle (red car in my avatar, beside my '71 Stage 1). It had the rectangle port heads with Hedman Hustler headers (2" tubes I believe) and I don't remember having any problem accessing any of the plugs. Sorry, I don't remember what plug wires I was running, but I do remember they were white. This was back in the late 80's - early 90's.
