At $3500.00 ready to run with .750 roller springs that's not a bad price for that much performance increase, but you have to invest in a matching manifold for for $1000.00 but you would also have to do the same with brodix's heads.

Caereful quoting flow number from one place to another. I know for a fact, at least compared on my bench, Self's bench is 25+cfm happy. Does it matter? Sorta. If they sell "flow" numbers, then they are playing a game of deception, to have you go there vs somewhere else, and its really frustrating trying to compete with places like that. I have to localy, and its hard to convince guys. I guess, when my heads that flow 20 cfm less, but make more power and the car is faster by many tenths comparitively, who's heads would you rather have? Ones that a sheet says they flow 420, or some others, that have a sheet that say 385 but run faster, and make more power?

Bicycles are pretty expensive now too. Wearing out shoes is not very cheap either.
I guess we can just work.

I didn't ask when i called, but Brodix claims 383 cfm flow with the same fully CNC'ed and flowed on their bench. but as someone mentioned earlier self might be falsely stating the flow #'s. They do use a 3/8" stud between to intake runners, possibly upping the flow, but 35 CFM seems a bit much to gain with with only 1/16" gain per runner around the head bolt.

PS, PWMAX, i like that Happy flow bench
