Rick MAKES Firecore, or at least has them made.

Since Prestolite now owns Accel, as well as jacobs and mallory, you can buy Accel wires with the ceramic boots that may be a help.

Throw some protective sleeves on those spark plugs and that should keep the wires away from the headers. S/F.....Ken M

It may help to get some short spark plugs like some lawn mowers use..

MSD tech dude was saying to buy another set and put this shrink stuff over it. summit msd parts

You guys ever use this stuff?

With straight plug heads I had to put a good sized dent in #5 tube for the plug to clear properly and for there to be ANY clearance for the plug wire. I ended up using the boot insulators that slip over the wire and look like header wrap. It works for awhile but eventually it still burns up the wire end. Always #5. I think if I had angle plug heads it'd clear better but it looks like it'd make one of the other cylinders tighter.
This is what I'm using. http://www.summitracing.com/parts/the-14260

I had cardboard in front of the radiator this winter to keep the heater working better and it caused the plug wire to burn a lot faster. Since I took the cardboard out, no more problems. So far. May have to build my own headers eventually. Probably when I finish these Stage VI heads.

Hey I appreciate the feed back. I think that I'm going to try what you posted over the stuff MSD said and see if can't over kill it.

What do you guys think?

Anybody have the part number for the shorter plugs that work. I wish that I could find that again. Someone had posted that on another mopar site.

Just got done watching an old Popular Hot Rodding video on headers, find the link on the Race engine page, there was something like 600 degrees F difference between ceramic coated and black painted headers. Something to think about.....Oh, and shorty headers are inferior to long tubes over the entire rev range (except for one point where they matched).

I had to run the "peanut" plugs on my 440 in the Ramcharger with headers.

Summit and Jegs sell them.

Hey thanks for the feed back...........will these fit 915 heads?

Do the 915's use a flat seat with the crush washer, or are they a taper seat?

If they are the flat seat they should work.

If they are a taper seat you could look at maybe the Chevy type peanut plug. I think they used a taper seat.

Ok, I'm going to have to pull a plug cause right now I'm not remembering off the top of my head. Thanks again for the part number.
