I am running SLP headers and AFR heads with the angle plug design and I am constantly burning the 6 and 8 plug wire boot on the plug. I was told they where L98 angle heads but I dont htink so and I think I even called AFR about it and gave them the numbers on the head and I think they told me thewy where angle plug. Im askingbecause I need to know if it just easier fo rmy to buy new headers from another make or buy new heads with either straight or L98 angle plugs/ Does anyone even have pics of the differance in angle and L98 angle heads?

 

I have spoke to afew guys using SLP headers with AFR angle heads. They have the same issues and have to pay close attention to a few plug wires. I have also spoken to the tech dept at SLP aswell and they suggested to me to get a straight plug setup if I order after market heads. You might want to invest in some ceramic boots to protect those wires.

 

thanks, I wonder if they sell a header flange spacer. All I would need is 1/4" spacers. I am running a dual cat y pipe so I can eaisly re adjust the pipes to compensate.

 

why don't you just run some type of boot shield for the plug wires? much cheaper fix than new heads or headers. are you running 90* plug wires? i'm running l98 angle plug heads (actual l98 heads) and hedman longtubes with the plug wires run underneath the headers with no issues whatsoever. i did my buddies wires on his car with some off-brand headers and 416 heads (straight) the same way and don't have issues.

 

Im already running boot protectors. But they dont help if the boot is still right up against the header tube. The boot wnds up getting so soft that it just breaks down and then the spark jumps out of the boot onto the header pipe.

 

i'd have to see a picture of your issue at this point.

 

the issue is that the number 6 plug boot is too close to the header tube and it burns. The number 8 plug boot is up against the number 6 header pipe. Plain and simple. The reason for my post was to see if anyone had the same issues as me and it seems that the SLP headers dont fit to well with my angle plug AFR heads. So, its either new headers or I dimple the crap out of the ones I have now. And trust me. I have no problem smashing the crap out of my POS SLP headers.

 

I use NGK UR5 spark plugs and they are much shorter than the standard plug and have had no problem.

 

Im running POS Accell shorties and its still not enough

 

Is there enough room to wrap the header tube? The material is not real thick and will reuce the temp.

 

im using hooker headers 2055's i got room to spare with them number 4 is really hard to get to the spark plug but my wires are not close to my headers

 

I have the same problem. 1 5/8" slp headsers and trick flow l98 angle plug heads. My #8 boot keeps melting becasue the very edge of the 90* boot touches the #6 down tube. I have a boot shield and small amout of exhaust wrap on the down tube to test, but I think it already melted again. I'm not spending the cash on new heads for a new motor. I most likly will just remove the header and try dinging it in. But most likly I'll screw that up and have to buy new heads. I wonder how much it would cost just to have a new down tube welding on for the #6 cyclider?

Give me your thoughts if if care to!

Thanks,
Jim

Oh yeah, I have shortie Accel plugs too for aluminum angle heads. I think they could be shorter, but thats the smallest summit had

 

I've used AFR 190 angle plug heads and now Brodix RR200 heads with Hooker SuperComps and have no issues with plugs or boots touching the primaries.

Accell makes wires called extreme 9000 and they work well in those cases I found since they have a aerospace coating on the boots themselves and they can lay on the headers and not get burned or break down from the extreme heat. they make custom fit kits for 82-92 camaro I rana set on my 83 cause I had the same problems and they worked great.

 

i know that you dont want to hear this but you could always dimple the header a little. just enough so that you have some clearance...cheap fix mabe not the right one though

 

I will be glad ot smash the header tube up to get this problem solved. its free if I do that way. Plus Ihave no feeling towards these piece of crap headers. They fit like crap and look like crap.

 

Hello All. Been lurking here for awhile but kinda of the silent type. Anyways, since we are on the subject I had a problem with the Hedman LT with the Dart Pro1's angled heads. Number 3 plug hit the number 1 primary. I also chose the hammer route to make it work. Just a heads up for someone planning a similiar combo. Also trying to throw in an exhaust clip for everyone to check out.

I run the fiberglass exhaust boots on all 8 of my plug boots. Extends the life of the boots if they are real close to the tube. Get them at napa in a 2 pack or summit in an 8 pack.

I ran my straight plug afr 190's with slp headers and had no problems, but you still need the fiberglass boots. Had to get the #7 header tube cut and re-welded when I switched to hooker 2210 longtubes though.

 

Sorry I didnt see this thread sooner. This is a huge problem with the regular angle-plug AFR heads. You either need a set of custom headers, or new heads, because no regular thirdgen headers will fit.
For anyone willing to spend the huge amount of money for AFR heads make sure you get either L98-angle or straight plug heads. Or just buy a set of Trick Flow heads for less money and almost the same flow rate.

 

Time to get out the hammer. I had the same problem with my old set of angle plug dart sportsmans and SLP 1 3/4 headers. I test fit the headers with the engine on a stand, #8 was hitting a shorty plug and #6 was really close, so it was hammer time. Use a ball peen hammer and go slowly. FWIW, I switched to AFR's with straight plugs and no problems.

 

Am running the AFR 195 angle plug heads with the SLP
1 3/4 headers and thier is difinately a problem. Am also
having to use a Auolite shorty plug and still have issues
with #8 plug.


Straight plug heads would have made it worse
What I did was to get some header wrap, 2" wide and
2 DEI stainless header ties for that area. # 6 plug also
pretty close. Trying to find some Raja plug ends they
use to sell that might also work.
Should have questioned SLP a little more on this and
they didn't mention this fact
