I would like some opinions of users of these heads either on a sbc or bbc motor. Brodix's website shows some nice flow numbers.

I run there 200cc head on my 11:1 350. I got the CNC chamber option, 2.05/1.6 valves. Had them milled to 60cc chambers,and got titanium retainers all for under 1600 bucks shipped with tax, through a dealer buddy of mine. I dont have any track time yet but i can say that right now im running a calculated 11.1:1 compression on 89 octane. The motor just keeps pulling on top end wich for me is 7,500+ rpm. Now as far as there flow numbers for the heads, Mike {wolfplace} lewis flowed a set of them identical to mine and said that brodix did not exagerate there numbers at all. He sent me the numbers and ill post them if you want but im too lazy right now.
Then there was the dyno results. He initially did a dyno run with a fairly mild 350, then sent the heads back in for the CNC chamber option, the test concluded that just with the CNC chamber option the motor picked up 30hp and 20 lb/ft of torque

Bit late on this post, but I had the 200CC RaceRites on my 406 SB stroker installed last year ( one of the first sets sold). Flow numbers on the CNC 2.05 valve were higher than Brodix advertized by just a tad. The 2.05 valve flows more than the 2.08 due to valve shrouding, so 2.05 is the way to go.
LOVE them period.
If you look at the low lift, mid lift, and then over .500, what you come to realize is you have a high low mid flow like an AFR CNC 195, and upper flow like a Vic Jr, all with 200CC high velocity runner. The Vic Jr heads high flow numbers come with a severe ( street) penalty of big big runners. The large runner Vics, only start to flow at 5,000 RPM, not good for the street however.
The Brodix heads are awesome with that small runner, you get unbelievable throttle responce, and torque, and all the upper RPMS you can manage to keep contained inside the block.
Do I recommend them, yes in deeddee. Not many guys would pick AFR a close second, but I have been Brodied.
