Gonna use a digital TQ wrench someday to find out, but my mech just hits them hard with the impact gun. Think he said the gun is around 110-120 ft/lbs. He's a full-time C5 mech and he's never had a car come back with a blown gasket, EVER. He does all his engines and H/C installs this way. Never broken a head off a bolt. I'm happy with this method. He's done my engine 3 times with no issues this technique.
Did you use some kind of sealant on the ends of the head bolts? That's necessary, right? I remember some sealant being needed on the block threads and other sealant necessary for some ported heads, but I forget what was up with the heads. My mech had to seal something on my ARE's once.
I'd go back to stock dowel pins and use a good GM MLS or Cometic MLS gasket.
How do you flush that milkshake oil outta there??</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">LOL, time to find a new mechanic. The torque/angle method is required to get the proper bolt stretch and clamp load on the gasket.
Using an impact is just plain being lazy.
