Here is the first iron OHV casting. Still needs cleaned up and final shot blasting. I think it came out very nice for the fist one.

From someone that doesn't know what they are looking at, I think that looks very nice. Where would the spark plug be located in such a head?
 
It looks like both the exhaust and the intake valves are in the head. Is the head based on an existing design or is it a new design?

I'm curious about the valve stem casting, does having it extend so close to the valve choke the air flow or is it a benefit, on the intake side at least?

It’s a copy of my original Scholfield 1930, which I loaned to him for copying. It was after Miller and before Cragar.

It's a close copy. I think my ports will flow better than the original. Flow testing will be done asap.


Thanks to hardtimes for sure.

How about looking at putting a quench type combustion chamber in there also while your at it.

After testing I will see if it needs it or if we can gain something. Initially, I just wanted to copy what Hardtimes sent.

Tell us about the valve train, is it one you are making, or is it one you are adapting from another motor?
Where are the push rods coming from, made special for this engine or from another motor?
On the spark plug question I assume those will be cut in after the casting, or can't we see them from the angle of the views?
