My combo:

Dish pistons at zero deck for 10.2 cr
Eddy's, pocket ported
Comp Pro Magnum steel alloy rockers
MP aluminum rocker shaft hold downs
MM lobe solid FT cam speced by Muscle Motors. 242@.050 duration, .55 lift, 108 CL
3/8" pushrods made to fit

On the cam, "streetable" is a personal choice. 242 degrees/108 cl has a "noticable" idle and is about as high as you can go if you are using power brakes. If/when I want more from mine, I'll work on head flow and keep the cam about where it is.
