Default Machine shop advice

I'm dropping my original numbers matching 69 400 block from my gto to the machine shop tommorow to get it ready for my 461 kit. I purchased this rotating assembly used from a member here a couple years back, it has a forged crank (not sure of brand) eagle h beams and ross dished forged pistons .30 over. I bought an aluminum torque plate as I'm using kauffman HP heads, should I have him bore and hone with the torque plate installed? Also This block is a two bolt cap version,should I run main studs and have the mains honed? I was thinking of using king bearings for the mains and rods if there good? The block is getting zero decked and kauffman says with my 56cc highports I'm looking at just under 11:01 compression. Any other recommendations on this engine? I'm hoping for 650-700 hp with a northwind intake and 1050 carb, here is a pic of the cam card on the hydraulic roller I'm running. I may switch to a solid roller lifter on this cam if it's beneficial, thanks for any help!
