Tim....looks like you've got most of the stuff nailed down there except for a cam and heads. I would definitely go with the steel crank since you already have one. I think the only company that offers steel FE cranks is Scat...and they're a pretty penny.
I myself would go with a set of Edelbrock aluminum heads...order them bare and assemble them usually quality valves...and valve springs/retainers/shims, etc. to match your cam. I'd probably go with a brand new Erson shaft mount and rockers.
I usually use Comp Cams stuff....so I'd go with a solid lifter cam...maybe the next step down from the cam you're using in your other engine to get the revs down a little.
I'd use an Aviad road race pan...Edelbrock aluminum water pump....Good double roller timing chain...And MSD ignition stuff. Oh yeah....Pentroof valve covers too.
