headers in way of spark plug

I've got tube headers on my 350 in my 66 Malibu. Can't seem to get #6 plug out, headers don't allow room to get a plug socket on the plug, and can't seem to get an open end wrench in there, either. Anyone else have this problem.......and a solution?

Re: headers in way of spark plug

Snap-on and Comp tools have shorty sp sockets with notches taken out of the side wall to get the socket over the plug and hexed for an open end or box end wrench to get it out for right now you will have to take out the header bolts unless you can get the socket to fit. My BB has raised exhaust ports and have similar problems I made a spacer flange out of flat aluminum stock to get more room(used a gasket for a template)

I had to take a new Craftsman boxed end wrench, the ones that taper 90* and offset, then I ground down the boxed end till it was about 1/8 of an inch thick. You must grind the entire boxed end to get it to slip over the end of the spark plug. I had to do this with my 882's and my AFR'S.

Re: headers in way of spark plug

i have taken a plug socket, cut about an inch off the end that goes on the plug, and welded a bar on it-takes me 3 diff tools to get plugs out of all 8

when your credit cards are maxed, have the limits raised

Re: headers in way of spark plug

I custom ground a socket as well.
Shaved it almost paper thin around the mouth of the socket to fit. Would hate to lose it.
Not just a header issue but combined with too small a slot for the plugs in my AFR's.

Sorry, not sure if it was mentioned, but, you could try using shorty style spark plugs to help with the space issue

This is true. My NGK VR4's are 1/4 inch shorter than a standard AC plug. I thought about buying that socket you see in Hot Rod, you know the one with that hot babe in the blue jean cut-off's. But I found if you get the #6 plug loose with the ground down boxed end wrench, then just remove the wrench and unscrew it by hand.

Re: headers in way of spark plug

The solution to this is to call the header companies and tell them we want headers redesigned for modern heads with raised ports and angle plugs, instead of giving us headers for 40 year old heads. If we stop buying the bad stuff, they will start making something that fits.

Re: headers in way of spark plug

I took a spark plug socket, and cut it off so that I had about 3/4 inch of the socket left. Then I took a slotted scrwdriver and welded it to the outside of it. I then bent this at about a 30 degree angle. This slides right on any and all plugs I have found to date and works great.

Re: headers in way of spark plug

Back when I was about 12................was riding my bike and found a whole toolbox full of tools in the trash!!! Can still remember carrying it home

One thing in that box was a double box end offset wrench. It's been belt sanded a bit and is a lifesaver when changing header plugs

Best tool I ever bought for spark plugs. Got mine from my brother in law who is a matco tools dealer.
