"There is no replacement for displacement".
I don't either. I think the original design was supposed to be a 335 with the 4 inch bore. In other words a destroked 351. I think a .060 over 335 would be the cats meow. It would allow for more RPMs. I had a good amount of experience building, modifying & serious street racing a boss 302 which uses the same cylinder heads, I get a bit irritated when people say a Boss 302 uses 351 Cleveland heads, NO a 351 Cleveland uses Boss 302 heads. The Boss 302 came first. Anyway I turned that Boss 302 too 10,000 RPMs, I think a properly set up .060 over 335 Cleveland might be good for 9,000 with a few more cubes than a Boss 302.By the way Gearge is on facebook also.He is always open to questions and helping others. He does not beleive in strocked Clevelands though.He likes them the way they were designed.
