edelbrock head and headman header

[lasvegas69charg]

hi. Is there anyone running the edelbrock rpm head and headman 17/8" header on a 383? It seems that the #6 spark plug is to close to the header and can't get the spark plug wire on without touching the header. I tried to dimple it but not enough room with the hammer to get the right dimple. Any suggestions?

What wires are you using ? Straight boot or 90* ?  The angled plugs make wire routing/fitment a headache with some headers. 

Can you post a pic ?

straight boot

Wow.

I generally like 135 degree boots for header applications.

You're going to need a kevlar sleeve on that one... and a bigger dimple.

Best bet would be to mark it then pull the header off and get some heat on it to make a nicer indentation. If it is too close it is only going to give you grief.

That is tight....as mentioned above, you will need more clearance 

Best way to do this is to remove the header and heat up the tube (with a torch) where you want to clearance it. Get the tube nice and hot and lay a socket on the tube and hit the socket with a hammer. I like to use the side of a 3/4in deep impact socket to make a nice radiused dimple.

alright I will give it a try. The funny thing is that everything else fit perfect

Accel makes a shorter plug. Not much shorter , but with an angled boot it might work. About 3/16 " shorter.
