Head flow and power differences question / discussion

550-600 to me, means I’ll be happy anywhere in that range or close to it.

I get that, but doesn't help with your question, 550 hp and less trick flow all the way, 600 hp plus Indy, 550-600 hp you could use either, 550-575 hp I'd lean trick flow 575-600 hp indy but also is a peak hp rpm of 6500-7000 rpm engine streetable to you ? It might be everyone is different, what about if you run 3.23-3.55 gears?

Trick flow the more streetable choice especially since your not overly concerned about the hp goal as long it's 550 hp or better but you could also just cam and gear it for the indys you got.
Is it worth buying a set of heads over ones you got? could always swap down the road if not happy with the indys.

It's all a series of compromises.
