Spark Plug Wire/Header Issues
I recently installed a set of Hedman headers with an exhaust which is an improvement from my last exhaust but with the Hedmans it seems almost immpossible for the plug wires #5 and #6 to not touch the header piping. I'd appreciate any advice to get around this minor hurdle. The new flowmaster exhaust with H-Pipe sounds downright mean! I had some hooker headers which were better as far as the wires but these hedmans are the ball type collector which doesn't require a collecter gasket and they don't leak! Thanks!

Re: Spark Plug Wire/Header Issues
I have the cheaper headman long tubes and the #1 tube comes back rightr up against the #3 plug . It already burned one end up . I put a junk plug in it , heated the tube , and used a deep socket to demple the header tube . I also bought a pair of the DEI flexible heat sheilds for the plug end . Makes me want a nice set of manifolds.

Re: Spark Plug Wire/Header Issues
I had a similar problem with my headers and the guys here recommended Accel Shorty Plugs and problem solved...

Re: Spark Plug Wire/Header Issues
I have those plugs. Matter of fact I just installed them as part of this tuneup I just gave the truck. New plug wires too and the darn header discolored the plug wire a bit where it was touching. Not too bad I only ran it a mile. How do you have your plug wires routed?

Re: Spark Plug Wire/Header Issues
Has anyone used the Moroso or Jegs brand Spark Plug boot guards?? I'd like some feedback before I drop 50 bucks on a set. They are 6" long and I think are just right to protect the wire right where it touches the tube.

Re: Spark Plug Wire/Header Issues
I have some of those woven boot guards. It helps, but it wont solve your problem. I have the same problem with the number 5 plug.

Re: Spark Plug Wire/Header Issues
First of all, Hedmans are the worst headers ever made. IMO. Especially with all the room that these trucks have under the hood. Anyway, here's how I took care of my burnt wires & it's a cheap fix.
I used "Spectra" header insulation boots for plugs #5 & #6. I used Summit 8mm plug wire universal set. I used "Spectra" rubber wire separators, & then used regular wire ties to hold the wires away from all the tubes. The ties are connected to the valve cover hold downs. This might not be "Bling" quality, but it works for me. Haven't had any problems since. You can get the Spectra things from Advanced Auto or AutoZone, etc.

Re: Spark Plug Wire/Header Issues
Well, I got under the hood and got creative with a few zip ties and re-routed the wires and ended up with something like 70 GMCer has and that completely eliminated the need for the boot protectors being that I have the shorty plugs. What I'd like to get is a setup like El Jay has and give it the neat look. Where did you get that setup El Jay-what brand? Thanks

Re: Spark Plug Wire/Header Issues
Mine has a big pita with #6 I have to take the header off to put it on and it just clears the header. I have the MDS red wires and they won't melt.
There was a pic on here of a very crafty guy who uses just wire ties to clean up all the wires. It looks sweet and NO wires touch each other or any steel..which is the way to go. I wish I could find the pic.....
