Raising power band with AFR 180's?

[MeanTA]

As some may know. Im buying Call911's ported AFR 180's. My plan has been to build a FI 383 with D1SC or F1....

But i know Call911 was having issues with the heads choking his 383 at 6,000 rpm. My thought is to go with a 355 and bring my usable power band above 6,000 rpm.

I can return my compstar 3.75 for a 3.48. With no issues since it hasnt been worked on or used. I know i will lose some lower end power. And i am fine with that. But would like to spin higher. Any thought or input?

And sorry if question is dumb. Still on learning curve with boost
