I'm leaning twords BB heads. I'll be running HD 3-7/8 jugs. SE 10.25:1 cast pistons, Big boyz or throttle city for the heads and I'm just going to stick with the same cams. Should wake it up a bit. Throttle city did the cams and dyno work last time. I was real happy with the end result. But money is money and $560 v.s. $380 is to much to ignore.
