My criteria though... I'd like to be able to retain my 6 bolt 15" Rally wheels.
Any recommendations or reasons to go with (for example) CPP vs POL vs Brothers...
Most of the vendor web sites say "may not work with factory wheels" - any recommendations on how to determining (before ordering) if the kit will work with my wheels?
Also - currently running 4 wheel drums with vacuum assist - I assume my existing booster is fine - just need a new master cylinder and prop valve?

Factory drum brake wheels don't clear the calipers on a disc brake set-up.
6-lug truck Ralley wheels came after disc brakes were standard on trucks so they'll clear.
Post a pic of your wheels. Are they original GM wheels or aftermarket?

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....
Cubic inches is like Indiana Jones with a cheap pistol.
