The lbz regulator will maintain rail pressure longer at w.o.t and i think it runs at 26.5 whereas the lly reg runs @ 24.5? You got a good game plan going, and some good advise, use stock gaskets, make sure the heads are flat and the valves seat and hold pressure and from what i have heard, dont use an aftermarket cam its a waste of money for anyone not competing, dont kill the messenger guys, that cam info is info thats been shared with me not personal experience
How much money are you wanting to spend? That usually is my deciding factor for what i am going to do.lol
I can think of alot better ways to spend 900-1000 on performance mods than a cam, and it doesn't stop at the cam, you will prob need different push rods, lifters, springs the works if you re cam...
