Routing Plug Wires Under Headers
Kinda stumped! I have been looking at the looms in Jegs and Summit. Jegs seems to have the best selection of looms, but from looking at their pics it is hard for me to visualize exactly how to get this done.
Can someone tell me the best looms to buy. A PN from Jegs are any place else would be very helpful.

I dont know if it`s a BB or SB, but 90 degree plug boots are the safest bet for both with a make up set and running down the back of the engine along the bell housing and behind the headers to the plugs. Safely out of sight with a clean appearing engine and normally with a lot of clearance around the header tubes.

Are there any heat related issues?

No more than the original will have. The clearances should be adequate with the 90 degree boots and a good set of headers as most of todays wire sets are heat resistant anyway. Just dont buy a cheap autozone lifetime warrantee set.

I routed my wires under the headers when I first installed my engine. It looks nice and clean, but it was too difficult to keep them away from the headers. Most were fine but there were a few tubes that were just too close to the block. I ended up going over the valve covers. That way I can be sure not to burn a wire.
Check out your clearance before buying anything. If you do decide to go under the headers, I believe Jegs has heat wraps for ignition wires available.

As pictured.

My 79 had sheet metal heat shields to protect the wires. You might be able to get some from a Chevy dealer or one of the catalog suppliers. They may have been chrome originally, but they were no longer resembling any form of shiny when I took them off the motor so I can't be sure.

It is almost incomprehensible that anyone here would misrepresent the facts.

Under header seems to work great for me. I use Accel 300+ which are wrapped in heat resistant sheath (Pro Sleeve). See link:

PS, But how do you like the plug wires, and those are 2 1/4 tubes on the Hooker Super Comps with tons of clearance. Tons of HP too.
Ferndog, nice clean engine bay on your Red

ferndog: I like those wires. Which looms/seperators did you use?
