Are you building it yourself? Which block/rotating assembly are you building around?
Are you staying 23 deg or going to 18 deg? Sounds like you have the major players figured out, but I'd get on a tech line and have nice conversation with each of those manufacturers. I am sure they can all fix you up with something, just depends how much $$$ you are wanting to spend and how far you are willing to deviate from factory type stuff. Raised runner, spread port, valvetrain geometry all will dictate your path. Out of curiousity how are you getting a 420? 4.155 x 3.875?

Sounds like a serious deal, good luck.
