Maximum Performance N/A 383 build. Input wanted from engine gurus.

I have trick flows on a 470 tunnel ram engine
It will pull up to 7k, but I make peak power at 58-5900 rpm and have a solid flat tappet so really there's no need to run it up that high.
Sometimes the bore is a little smaller on 383s for trickflows.
I have a 4.375 bore and had to notch the top of the cylinders, not because the valve was close but the combustion chamber was bigger than the bore in that area, so my mixture was just coming down and hitting the deck lol.
Too damn bad you live all the way over yonder.
Id pull the top end off of my 470 and throw it on that 383 basically so you can test it out and see if that's going to meet your goal.
