As far as where to get parts I order most if not all threw RockAuto and a radiator threw 1800 radiator. The head gaskets I use Maul or Felpro head bolts are extra. I always send my heads out to have them resurfaced and have the valves cut worth the money for me. Change all the coolant hoses and the heater valve. I use a torque wrench for peace of mind Harbor frieght sells them pretty cheap the work well enought except for the crankshaft nut is out of range except for the expensive one. I run a Die over all your exhaust studs.
Good Luck :rofl::rofl:
