W2 valve size recommendations

A wait for the actual members that machine parts. I e done some home head work before. Minor rebuilding, spring seat area machining for larger springs. EZ stuff.

I could suggest that you use the largest intake valve you can get in there, within reason, no trick work. Thinnest stem possible. But that’s the no brainer right?!?!

I also have a bare set (4 heads actually) not quite ready to be messed with.
I’d like to know the actual valves and part numbers needed/suggested to be use in a similar application.
