Thanks Beater!
Currently looking for the right material to replace the intake valve guide bosses.
Going to jig the head up and measure locations for the intake guides, then machine them completely out and press in new guide boss material that is to be welded in. Also filling in the intake spring pockets with about .2 of weld.
Then will re jig it up and machine the bosses for new guides and spring pockets.
It is a process.
Here are some interesting pics. It is a cross section of a Duggan shaft mount head. Notice how little support there is for the intake valve. Well the head I am working on has even less. My spring pockets go into the intake runner and the valve guide seal area is gone.
