After reading your page I noticed the thread sealant. Do I need to use High Temp (Permatex High-Temperature Thread Sealant) or Regular sealant (Permatex Thread Sealant with PTFE) for the 4 bolts that hold the water pump to the engine?
Yes- on the bolts that go into the water jacket.

Carb to intake torque is about 15-20 ft/lb for a 5/16 fastener. Use no more than 12-15 ft/lbs (spec is 144 in/lb) on the long through-bolts if bolting on a Q-jet or the casting can warp.

If you're using a thick insulator gasket, retorque until it takes a set, don't overtorque it hoping to make it stay tight.

I always recheck the carb to intake bolts on a new build along w/the intake to head and header fasteners after every heat cycle until everything settles in.

Truth be told, you can just tighten the fasteners by feel- snug them down plus "a little bit".
