63 lbs-ft. biggest thing to make sure of is that they are tight. You really don't need to torque to a specific torque. But the specs are here for your needs.
Depends on specific engine ( truck/car, vortec/ non vortec, year, etc). Best place is to call any of the chain stores. They can print all those specs out based on the vin and year of the vehicle.
On a 1968 Chevy 350 small block it is 60-70 ft/lbs with sealant applied
When torqueing the heads, it is helpful to start at around 25 ft. lbs. and torque all the bolts, then go to 50 ft. lbs., and finally, your specified torque. Doing this in increments will help give a nice even torque to the heads
On that set up the computer mainly sets your timing. It reads the timing off of the crank sensor, cam sensor, it tells the injectors and coil packs what to do.
