I have a 4106 to install Jakes on it has the old style heads ? is where do they bring the wire out do they drill the valve cover or the head for the leads.
I know where they come out on the later heads they have plug to remove.
If you are looking at the head the older models (hump back) don't have the plate with the 2 bolts for each cylinder on top this bus has both styles you GM guys help me out here
good luck
Cliff,, the easy and best way is to drill and gromet the valve covers above the "puddle" line.>>>Dan (oh and its not a GM thing,, its a Detroit thang )
Clifford, I have two sets of old style and a set of two valve heads and they all have the plugs in them. i would say clean a little better get a good light and put on your glasses. LOL
Don
They are clean Don and they are not there and you know I don't wear glasses lol anyway I drilled the blank off for the governor rod on the opposite end off the head and tapped it for 1/8 inch seal plug that works.
I didn't won't to drill his nice chrome valve covers and fight the wire every time you remove the valve covers
good luck
You really DO NEED glasses Cliff,,you can't tell chrome from polished,, and a disconnect on the wire outside the cover works great.>>>Dan
Got me there Dan lol
good luck
