Got this really rough Duggan head about 5 years ago. My machining capabilities have came up with time. I am now ready to try and fix her up.
Originally it was a shaft mount rocker system. Someone years ago decided to mill it out and probably install a stud mount system of some sort. It must not have worked, because it is all gone.
The spring pockets had been run with no steel spring seats and the springs cut though into the intake ports. Bet that introduced a bunch of oil into the ports. Someone welded that up too.
The exhaust guides and all valve seats look new.
Intake guides are gone.
This is a canted valve arrangement.
So, I have it mounted on the CNC to get the bolt pattern that someone drilled into it. Need to duplicate it for the piece to be bolted in.
Wish me luck. This will take a while.
