Looks good, are you worried about all the leverage out on the end of the crank? The front main bearing is sure going to have a load on it.
That was discussed extensively with Crower when they made my billet crank. I'm not sure what the magic is they did but it's all BBC. Also when BHJ made my damper it has a BBC seal on it. The damper that is on there is a slip fit mock up hub they made for me at no additional charge.
