Call Self Racing if you want set of 18 degree heads that work as well as the 15* or better.
they have the 18* clone heads
cfm on intake at .750 420 -430 cfm
cant beat it they cost $3500.00 set complete

420-430 on clone heads,how big is the port? Bill

clone heads?
:lol:

They are actually brodix 18 degrees with a some what different approach in the runners. Where brodix fully CNC'ed flow 383CFM Self's flow 420CFM, i've talked to them they have put port savers in the intake runners that open up the extra flow.
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.

How many C.C. in the int runner? 420 doesn't mean anything without knowing the runner size.Bill

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?

Boy' Do I know the feeling. :(

Bicycles are pretty expensive now too. Wearing out shoes is not very cheap either.

I guess we can just work.

Don't know Bill,
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
