Reaching plugs with Hedman headers

jrc4y4 said

Having issue accessing my rear two spark plugs on the driver side to tighten them (5 and 7. I installed headers for the first time, slipped the plugs in and I can’t get a socket in there. It’s 13/16. I don’t think I could even get a wrench in there. Do I need to back the headers out and hope I can make it work, or is there a tool? Or do I need to basically fab up a tool? I don’t have a welder but can have someone come up with something if needed.

Go buy a powerbuilt swivel 13/16 spark plug socket, use a 12" extension..put the socket onto the plug by itself..position the female 3/8 drive portion up between tube and valve cover.. insert 3/8 12" extension and using a 3/8 ratchet ...loosen it half way ...remove 3/8 12" extension..and by hand unscrew the socket/plug. Install in reverse.
I can change all the plugs in 20 min or less.

That's how much room there is.
Here's quickly made video of mine on the subject. @jrc4y4
