Picked up a 1983 Dodge TD today

check your timing, you may be 180 off. This is a common problem with head repairs. Missing the cam gear timing by one tooth is another very common problem to happen.
Prime your injectors also, possibly you have a vapor bubble locked up in the line.
The head looks fantastic, luv to see new parts like those.

I'm with droppedmitsu on the color. Not sure about decals, but the color is nice. If you ever get a chance to make a video, I would luv to hear what that pipe sounds like with it coming out of the bed that way.
