Porting Big Block Heads

I don't know what magazine the articles were in originally but its in the Hot Rod Magazine Archives now. Back in 1998 they did a 3 part article on porting Mopar Big Block heads. Here are the links if anyone hasn't seen them before:

Part 1: https://www.hotrod.com/articles/cylinder-heads/
Part 2: https://www.hotrod.com/articles/cylinder-heads-ii/
Part 3: https://www.hotrod.com/articles/cylinder-heads-iii/

Has anyone on here copied what they did with a set of heads? I am really interested if anyone is running around with the 30* intake seat that they liked so much in the article, they claim that the 30* seat gains a considerable amount of low lift flow and doesn't hurt high lift flow, says it would make a good street head.
