Help choose cam for vortec 350

[82Scottsdale]

Hey, well im having some trouble finding the right cam for my older 2piece rear main seal 350 with vortec heads, edelbrock proformer, and holly carb. I bought the block and its camless so im trying to find one. The heads are completely stock, im looking for torque, hopefully a little lope in the idle. The truck is a 82 k10, lifted 9 inches, 4.56 gears on 39's i wanna keep the stock stall TC in my th-350and its my DD, i use it for mudding, roasting tires and all that funn. I was looking at these three cams. Add what cams you would also have me interested in

what one do you guys think i should order? and what one would sound the best and proform the best over all and would they work with my heads?

are you running an electric fuel pump or mechanical on the block??? flat tappet or roller lifters??? big lift and big tires are needing tq down low.

mechanical on the block and flat tappet, i know thats why im looking for a torqey cam, im wondering what one of those would be best for my engine and if they will actually work with my heads, cause the heads can only handle about .480 of lift, and if not if someone recommends a cam for me.
