Richard, the blue stuff on the heads is mostly for the valve seat lapping. The back of the valves and the seats have to mate perfectly and he uses the blue dye to see what needs work.
One neat thing about 911 heads is there is not a lot of porting necessary. He cleaned up any and all sharp edges. If you took out the valve you can just about pass a golf ball through the ports.
Two of the Dilivar head studs were not tight. The studs on the cylinder that was leaking. All of those studs are in the trash can. New Raceware head studs and rod bolts are supposed to come in today. If all the rest of the parts arrive as expected he may have the engine finished this weekend.
He only does this in his spare time. He has a full time job. He does a Rickey and goes in at 5:00 AM for his full time job.
This shows the boat tailing and what he cass "cat ears" that match up to the bottom of the clyinders.
