Need help
Changing plugs on my 440 but have problems removing number #1 and #2 plug ….no room to manoeuvre
Is there a speciality tool out there? Has anyone else had this problem…..I run Doug’s Headers. Really tight

Also..
#6 plug has been removed and new plug threaded in by hand but cant get any sort of socket or tool to tighten plug
The header is so close I can’t get a socket or a wrench to set square on the plug to tighten
Any suggestions? Anyone ran into this problem? Is there a specialty toll out there?
Any suggestions would be appreciated
 
Hammer, pry bar,open end wrench. Probably need to massage the header tubes to make some clearance. Pictures?

Can’t get it from below with box end or open end wrench?
 
Agree with Bird lover most of the time its easier to get to them from under the car. Headers make it harder but doable.
 
A few tricks I use for header cars:

1. Instead of a ratchet, use a hex-end wrench on the end of a spark plug socket.
2. Cut a wrench in half and use the stubby box end for tight spaces.

Sometimes ya' gota' do whatcha' gota' do.
A fat six-point plug socket had issues fitting on a plug or two with these older TTi below.
Maybe try a thin wall 12 point to tighten and break it loose if you don't want to hammer header tubes for clearance.

Get lose and use a piece of 3/8 rubber hose or smaller and turn out or on reinstall then tighten up below or dimple header for the future
 
#6- As was said, I use a spark plug socket (remove rubber liner) with a hex on the end and an offset box wrench from under car.
#1- Plug socket, no rubber liner, 3" extension and ratchet from on top. Worked for me on Dougs and TTIs.
#2- Shorter offset box wrench reaching in from the front on top. Again, I've had both brands on this car.
 
If you have the right tools, and the right technique, spark plugs on a BB with headers is a fairly easy job. Box end wrench, u-joint adapter, different size extensions, etc. Perhaps post a photo of each situation for a more concise advice.
 

$86 !!! :eek:

I have Doug's big tubes on my 440 and use like already stated. Open or closed end wrench on a plug socket, closed end on the plug. Rubber hose to install. #6 can be easier underneath but I manage to do it above. Hardest part I find is getting the plug wires off and back on. These old fingers don't have the strength and flexibility that they used to.
 
#6 is not all that fun with stock HP exhaust manifolds. But position right, it can be done with a standard 3/8" plug socket. If header is that badly in way? I wouldn't waist time. Lossen up the header.

I believe the RB raised block has the highest deck height of any classic big blocks. Making the 440 widest. The hemi with its heads is wider, but plug location is not an issue. Lol.
 
Twenty years ago I switched to 5/8" plugs. Only come in 3/4" thread reach as far as I know. I made 3/8" spacers to get the correct 3/8" thread engagement. Remove washer, fit spacer, re-fit washer. You have faaaaaaaaaaaar more choices of plugs that use the 5/8" hex [ Plat, Iridium etc ]. They are also more compact overall, ideal for tight spaces.
 
back at it today!!

I picked up some “crows feet” wrenches ..maybe that will work Thanks for all your suggestions..I’ll keep you posted
I’ll send pics too
 
I have to go through the inner fender access holes for the upper control arms alignment bolts on some of my cars with headers to do a couple of the plugs including #6.
 
On passenger side of engine, I unbolt the alternator from the lower strap, and swing it up out the way. That way, I can get my arm down in there to loosen plugs. This is with HP manifolds on 440 in my '67 R/T. Still, I have to do about half the plugs from underneath. More ignorant than changing the oil filter!

I agree , the price is rediculous. I bought a pair of those off the Cornwell truck about 20 years ago for about $25. I was reluctant to spend that but was curious as to how well they worked.
