I guess I'm confused, I see a lot of bracket cars at the track running stock heads, I see stock eliminator cars running stock heads, and I'm guessing these Stealth heads flow better than stock from what I have read.
Why would they not be race worthy if they flow better than stock both out of the box and ported?
I would think it would depend on what you wanted to do and how fast you want to go. I see no reason why a set these CNC ported Stealth heads wouldn't be fine for a 3500lb bracket car running 10's all day long.
