You do not want to tighten Raceware bolts more then 65 pounds. When you do, you start to pull the front and rear of the cylinder head down which means your bending or curling the head, and everything above it. This bending depends on the gasket your using in between. The Cometic would resist this more then the stock style. According to Raceware, anything above 70 pounds starts to curl the head. So it would seem 65 pounds even on a Raceware may be to much as well as anything above 70 on a stock stud.

+1, some feedback would be welcome.
I am also using Raceware studs on my 2.7 head, stock headgasket, no O-ringing, head torqued at 35/50/65/90 lbs.ft, and when running over 15psi the coolant still seems to be seeping into the cylinders.

I too use a techangle AWSOME tool. Although you are using the 3/8..... I opted for the 1/2 inch one because its range is better 12.5 to 250 ft pounds and on the bigger stuff its easyer to use smoothly. Bought mine for 415 new from my snap on rep. I tq my 951 heads using a widefire to about 75 ft pounds final tq.
