The best way to determine your runner IMO is to know what RPM's you will run. If you shift above 6,200....then a 220cc runner head is not overkill at all. If you are below this RPM a 200cc runner head will be fine. A 220cc head will not benefit you at all unless you spin the engine higher than 6k - 6.2K

I agree. The 'exception' would be the only time the motor saw the high side of 6K. 99% of the rest of it's life is going to be spent on street duty.
I think I'll use it as is & see how it goes. I've never had much exposure to the 350 vs. 400ci combo's w/the same cam. Back in my younger years, my roomate had a 69 short fleet, 406 w/a set of mild stock heads, stock style pistons, Comp 292H cam, t-350 w/a kit, 3.73's & 325-50-15's.... I remember it pulled like a freight train. This should have more compression & better airflow capabilities for an even better experience.
Thanks for everyone's input & experience.
