My brodix br7 head flow chart Let me know what you guys think. I know Brodix advertises these heads to flow more out of the box, but fyi we flowed them out of the box and they flowed much less than Brodix advertises. my cam is about 750 lift so i think i should be good.

when we first flowed them out of the box (already cnc'd from BRODIX), they did only flow around 390 CFM at their max. we had to do additional porting to get them to hit 412 CFM. Another guy on the CTS V forums has the same head and he was able to get his up to 420 CFM. Clearly Brodix's cnc program needs to be updated

What did brodix say to you as to why the numbers were so low?
Also what BR7 heads did you get? i have the BR7 STS 273 BS heads not the regular BR7

Yea man id be pissed. i was pretty pissed i had to have additional porting done. FWIW, it seems that all companies exaggerate the flow numbers. Who did you end up going with to replace the brodix? what do your heads flow now
