Default Torque Specs

Im adding the ZZ4 fastburn heads on my car does anyone know the specs on this? I found 22lbs first round then 80 degress second round and 80 degrees third. 67 Degrees for short bolts. Since I have no way of measuring degrees is there a ft/lbs i could use for these degrees?

Not sure about the intake fitting but as for tqing, 22-25 (depending on tq wrench) 1st, 2nd time 45ft-lbs, 3rd- 65ft-lbs. Don't worry about the degree stuff. You will notice the difference when you are tqing them. The short bolts won't turn as far when you get the click or hit the 45 & 65 points on the guage (most accurate type of tq wrench). Just make sure to follow the proper sequence. If your are using studs, them contact the stud manufacturer and go by their specs.
First and foremost...make sure your threads are clean and tapped and you use a teflon sealant, not silicone, for proper tq readings.
