George- A couple of things after reading you response
1) Kelly has the pattern for the CHI 3V head and has agreed to cast one up for me when I am ready. Deposit is down on that item.
2) Valve train - The 1.7 ratio was based on input from Dan Jones that said 1.73 or greater would create unacceptable bind with the beehive spring. I did realize that I was probably going to have to combine the beehive spring with Crane lifters to get the rpm out of a hydraulic roller valve train
I was thinking Jesel Nascar timing belt. Your opinion hear would be valued.
I had already planned for an upgraded oil pump drive shaft.
The distributor drive would be one of the new composites and I will have a machinist attache and align it properly as the gear on my last motor
