Building a 42 John Deere-B for pulling, and want to use oversize valves. Can I use JD-A valves? Suggestions welcome. Thanks!

I have 44 B that i used unstyled A valves,runs good.It also has two inches on the crank.This setup puts it at about 50 hp.It is pretty tough in 3500.

What are you running for bore size? And what kind of cylinder head are you using? Thanks.
