Spark plugs hitting headers
Posted 21 March 2012 - 09:08 PM
How do you guys route your spark plug wires and how do you deal with heat coming from the headers?

Even with those, a couple of the boots were very difficult to get on, but my problems went away. Worth the $100 or so bucks. They survived my engine initial startup and break in, where my headers were glowing a nice cherry red, so I think they will last a long time

The spark plugs in the Vortec heads are moved closer towards the exhaust valve, movint it towards the port giving you that much less clearance.
Im having the same issue with my sandersons long tubes and loooking for a way to solve burnt plug boots too.
Why build it if your not going to drive it..........

Looks like the prices have gone up since last year or whenever I got them. Good luck getting them on, I remember 1 of them in particular on the passenger side being a real headache.

Called up Summit to make sure that I'm buying the right plugs, and apparently the Accel Ceramic plugs wouldn't be right for me. They're all appropriate for HEI distributors and I have an old points style.
Huh? My kit came with both HEI and standard boots...Maybe you should give Accel a call. I did before I bought mine and they were pretty helpful.

I am not sure if the B Body LT1 motors use them.
Go to the junk yard and grab some, you may have to grab some from more than 1 car as they are not easy to reach.
Here is a set on Ebay for less that $20
Taylor has some metal jackets as well here:

Were your boots physically touching the headers? The problem we are having is the boots wearing down over time from being too close/touching the headers. Aluminum would make the problem worse, as it conducts heat much better than silicon/ceramic.

Good news is that I got my headers dimpled right by the plug heads, and now that I have extra clearance between the headers and the plugs, the car is running great.
