Start from the center and go outwards in a criss cross pattern. If you have alum. heads torque them in 5 lb increments to 18 ft-lbs and to 24 ft-lbs with iron heads.
Hmm.. good thing you said that! I probably wouldn't have gave it any thought because there's a few that look really rusted!
Does ARP sell a bolt kit and should I put any loctite or threadsealer on them?
And what Grady means by tighten them a "few times," really means about 6 or 7.
I had to run the pattern 6 or 8 times before the bolts were actually tightened to the right torque. As you work your way out from the center, it seems like the ends will pull the middle bolts back out, and the middle bolts will pull the ends out. Weird.
Just double and triple check yourself before you go on...
