450cfm
My warp - 6 heads are advertised 460 cfm as cast nothing but a gasket match . My 541 dynoed 1025 at 7500 rpm . I was quite impressed . They are back at Kauffmans shop to be cnc ported in preparation for the new aluminum block 535 . Don't know it I will dyno this spring or fall once race saeson is here it'll hit the track
