Ok, at long last, I was able to ram up the waiting molds and do a pour. Everything turned out great, and no accidents.
I pulled off the valve cages and sent them to the iron foundry, didn't want to inset valve seats through a 7/16 hole.
Hope I get those parts back quickly. I've had to do the aluminum compromise on the rest of these parts. Still need to do the
base and crankcase, they will also be going to the iron foundry. I found from doing the cylinders, I will not be able to melt
enough metal to poor the crank case in my crucible. What I have will keep me busy for a while anyway.
