bbf C&C motorsports pro18 heads?

not sure if im missing all the lastest news and im late or if these are new but i just stumbles in them on the bes website, im looking to build a new motor and looking in the 638-700ci range, whats the info on them, i tried calling both C&C and bes, looking like they take the c460 style headers? what valve train and pistons? intake im going with custom, has anyone use these and whats the results? whats the best cubic inches they seem to work with and are they worth the buck for doing so or are the existing stuff out there just as good?

I believe Charlie has messed with a set or two

They are basically the same as BT Thor heads

any good or decent results? dyno time and passes down the track?

I've had my hands on them, but I dont have any flow numbers to share. I believe Tony Bisloff at BES has built some engines with them and has some track results. Call him.
