One of the reasons I want to run rectangular port heads is they really don't start working until the rpm's get up there. So, I won't be frying the balonies out of the hole...just hooking up. By the time I get the real HP going I'll be moving.
I know that there are guys out there running the 198 intakes to keep the power down out of the hole just for that reason.
That's how I ran my 427 Nova that I built and it worked wonderful, even with P215/70R14. I never got a chance to take it to the strip to see how quick it was...I sold it
but here is video of my Nova from a while ago when it had a tired 69 396 325HP, M20 with 3.73 gears.

BTW I ran a 13.93@100mph with the air cleaner off. Earlier I ran a 14.08 and a 14.06 with the air cleaner on. That was my first time ever at the track. And the brake lights were coming on every time I pushed in the clutch.
