Default L98 Header Install - Any Pics?

Am considering some long tubes and am concerned with heat issues. Can someone post some pics or email them to me. Specifically with spark plug boot issues. All input appreciated. 1985 L98

Thanks for those pics. They look great. Are those TPiS pipes? They really come close to the fuel line.

I used the stock metal clips.Then bought a new set of plastic wire holders from mad to put on the clips and routed the wires accordingly There are two on each side held by two bolts each. With the headers it was necessary to grind off one bolt hole on each clip to clear the flanges and just use one bolt on each with a lockwasher for each. Sorry, I didn't take pics of the clips before putting on the wires so you could see how I grinded them off.

All posted have been Hooker, TPiS may rub the plug boot on #5 and #7, kinda depends on what plug wires youre using.

you should also look at my website before proceeding

I'm not sure what 86Pacecar's are but I dont think they are hooker. You are right about mine but I think his may be coated headmans. The pipe looks smaller and the shape is more elongated and that #1 primary tucks behind the three and five. Whereas the one on the Hookers goes in front.

Ok now it's getting confusing in here. 86PACER's are Hookers but I dont think 86Pacecar's are.

Thought so but couldn't make it out for sure. I just knew it wasn't the Hooker super comp badge.

Man it is so easy for you guys to reach your spark plugs, I have the same hookers on vortec heads and it is a pita to get to a few of them. I have to use an open end wrench to get to 2 of em. I also had to use shorter plugs and the kevlar sleeves so the wires wouldnt burn up!

I use DEI Protect-A-Boots with Stainlessworks headers.



Thermotec offers a different product



In addition to protecting the plug wires, I also have various styles of
heat wrap on
  • the brake lines from the master cylinder
  • the fan switch
  • coolant temp sensor
  • oil cooler hose
  • something I can't recall near the EGR pipe
  • something I can't recall near #2 primary
I also have wrap for the starter but have not installed this yet.

Might have overlooked mentioning something else, but you get the idea.

Where did you get your shorty spark plugs. I've been looking for them but nobody here has them.

Accel offers plugs with short insulators. For instance, their #276 is also
available as #276S.

Look these up at Jegs and Summit. The Jegs site will display a list showing
conventional and short plugs where available.

There is at least one other brand that offers short plugs but the name
escapes me at the moment.

Default different looms

Same headers as everyone else the Hooker Super Comps with the air injection tubes. I include the pics because I didnt see any other with this type of plug wire loom. Forgot the brand name but got them from Summit so shouldn't be too hard to track down. Had to modify the bracket by the number 8 cylinder but other than that they work well and route the wires out of the way and very neatly. Boring gray TPIS wires so not very bling but works well.

I used some DEI Fire Hose (supposedly good to 2200*) on the oil cooler line, that seemed to be the only real suspect area (clearance is about 11/2" there) visible in pic between 5 and 7 cyl. The other thing I had to do was bend on the heat sheild on drivers side to clear the collector. Hooker 2149

You don't think those brake lines exiting down from the M/C adjacent
to #7 primary need a little shelter?

I forget which company offers it, perhaps ThermoTec, but one of them
has a wrap with a hook-and-loop (Velcro) seam that saves the day for
items you don't want to disconnect if you can avoid it (like the brake
lines). Just turn the seam to position this outboard of the heat source.

Nice work on that engine & compartment - it is great to have the
journey you've taken with this car turn out to be so scenic.
