I’ve incorporated the thrust area into the actual cam. The Honda and V1 has a washer that bolts to the cam. This change allowed me to strengthen the front of the cam and also do away with the cam gear adapters.

On the front of the cam I had 3 dowel holes drilled. The only way to adjust the cam timing on the K24 is to buy or make modified cam gears with offset dowel holes. The single dowel gives you 2.5 degrees adjustment at the crank per hole. By using three holes I was able to split that to 1.25 degrees advanced and 1.25 degrees retard.  This is a big improvement over V1 with the adjustable hubs.

The cam is semi finished from Crane. The lobes will be dialed in buy whomever ends up doing the final grind.

Sorry for not updating this for a while but since this is a sold head the progress is subject to the new owners available time.

This is the head with all the initial machine work done. I pressure tested the casting at 75 psi and it held fine.

I messed up and spot drilled the wrong hole pattern for the exhaust flange. The head is 356 heat treated to T6 so I wasn’t too interested in putting any unnecessary heat on it by welding them up. They are behind the exhaust flange anyway.

The owner of the head did his own port cleanup. He is going to finish blending in the port match after the valve work is done.

The head has been vacuum resin impregnated and is at the machine shop having the valve work done.
