I'm kinda of the opinion of using a HC cylinder head, counter weighted fully balanced crank and assembly, somewhat lightened flywheel with V8 clutch and Bill Stipe camshaft. I would just as soon use the original non adjustable lifters.
But, that said, as long as the work is being performed, why not install over sized valves, open the ports for possible use of '32 manifolds and carburetor.
