small block headers

And your car isn't a track is it???

Or 540-550 with a better set of headers. :-D

It's all a trade off, fit vs. performance, what you are after/goals, and some people don't like the truth I guess, Sam and staff included.

I can tell ya' first hand dyno's are NOT the tell all..lets see a comparison where it counts at the track,time slips don't lie...
