Of course we realized we can't run this head in Production, since it is altered
. But we like it so we are going to finish our little test.
Rich finished the last port during the week
Birds eye view of the exhaust valve seat
Center ports, notice the crud in the water passage?
Casting wire still in the head
I cleaned up the edges of water passages with a dremel and a grinder using various bits. The main goal was to clean away loose material
Notice the hole in the front corner, those were small pockets that were just peeping through. One for each port. I drilled them to 9/32 and tapped for 5/16 fine thread.
Here is the center plug shaped out of cast iron, and a bolt in the hole I described above ( sorry for the blurry photo )
Plugs and screws ready to glue in
Glued, next the head needs to be re-machined
Thats all for now. Zenon
