W2 valve size recommendations

Thank you Doctor Rose.

And tip on who’s valve or parameters of the valve to be used in a racing application?

I myself have that tunnel ram I wish to use in a couple of years time in retirement. FWIW, the next comment may change a thing or two, so if you could cover two birds with one stone.....

I really don’t have a wish to spin it rpm wise to high. I’d also like to run it on a stroker rather than a 340 CID.
In your opinion, how would you approach both angles of a big and small engine set up?

Im in a very similar boat as the OP @replicarracer43 who I hope doesn’t mind me jumping in on his thread to much considering my future path I want to walk is being done by himself now.
