i think they are like 10.25:1 compression on a 400, i run them on my 455 with sunk top pistons, from what i understand all the d-ports run pretty close on the flow #'s but i'm sure someone will know alittle more about them than i know

i know they are good 4 barrel heads with 2.11 1.77's and have screwing studs and work will on my motor with a little home porting!
