    BBC 291 head flow data

    Does anybody have any flow data for the 291 Rect port BBC heads ? I've had these for quite some time and they have had some work done to them (stainless valves 2.25, etc.). Am going to put these on a little 396 that I'm putting together for my 68 Camaro. Any help would be appreciated.

    I've been to MORTEC many of times but have never seen anywhere that they list flow data on heads. I've also Googled many different ways and once again have never seen any flow data on 3964291 heads (either stock or ported). Thanks for your response though.

    I looked in that site and didn't find anything the 3964291 casting. Found a BBC rect port but that's about it.
