It has been so long since I have had manifolds on my car, I can't tell you for sure. I have linear looms with headers. They bolt on to the outer valve cover bolts, so if the manifolds go above the bottom edge of the valve cover, I don't think they will work.
The rams horns tend to bake the wires pretty good, when engine is hot and still hood down, like parked, the temps from them things can bake bread...
and kills wiring quickly.....ME, I say put on a decent set of headers...
If by linear wire looms you are referring to the ones that run lengthwise along the valve covers allowing the wires to to the same and drop down to the plugs, they do not work with rams horns.
Gene, I definitely agree that the stock exhaust manifolds do cook wires and headers are better, but for those of us not ready to make that change (I am just keeping the car running for a few years of enjoyment before a rebuild) or want to keep the stock manifolds for factory look, anyone have a suggestion for what seems to work?
Wade, GM still offers the bracketry and inserts for the behind-the-head and under-the-manifold spark plug wire routing. They also still offer the heat shields to help protect the plug wires from the manifold heat. I just ordered 2 sets yesterday at a local Chev. dealer. Dr. Rebuild also offers these items. I did not write down the GM part numbers but the parts will be in Tuesday or Wednesday. If knowing those numbers is of interest to you, please let me know.
Thanks. I know they are available and might end up with them for mine. Not sure. though, that I want the hassle if wires need to be changed later. They should also require the manifolds to be removed to install.

I beg to differ. I ran set of these looms with rams horns:
Ran a set of 8mm 180 degree boot wires, just have to loop them around the manifolds. With my blue car and blue wires, it looked nice. They held up until I broke in a cam and melted on boot, manifolds where glowing red. :eek:

I stand corrected. I couldn't get the ones I bought to work right. NOte to self - get bigger hammer. :D

Thanks Fevre
No problem. :cheers:
The key is the 180 degree boot, it allows the wire to loop out away from the head. I should mention that I also have angles plug heads so that also helped direct the wires away from the manifolds.
