Hey guys just installed arp studs and getting ready to torque down heads. Question is i pulled up a sequence from identifix and its kinda not making any sense. I know arp says to follow manufacturers recommended sequence and tighten in three equal steps to 125 ft lbs. My question is what should i start the three steps at? 30 60? Identifix is using so many degrees first sequence and this that and the other. Is there a ft lb number to go by ? Its early and i tried calling arp but no answer yet. Any help would be appreciated cause i am trying to get this thing running this weekend and ready for memorial day! Any body make sense of this sequence?

Yea bud, thats the normal torque sequence for just about any head gasket. The torque sequence goes in a clockwise, conical, rotational pattern startig from the inside and working outward to equally distribute the load as it is torqed down. It is important to follow the clockwise pattern or the head could be distorted and therefore ruin the gasket.

Thanks i ended up finding an actual photo of the head itself in my gm service manual i forgotten i had. My question was about the sequence that identifix had on there web page it does not even match the lb7 head bolt pattern.My appologies i should have had another cup of coffee before i posted this i would have realized i had the gm manuals. BTW if anyone needs any info these things are slammed packed full of it just ask.

Keep in mind that 19-22 are the little gold bolts.

Thanks i appreciate the help i was just trying to make sure i dotted all the i's and crossed all the t's. I've done alot of gassers but this is all new to me. I gotta say there is an unlimited amount of information here and alot of guys that are more than willing to share information and experiences as well. Without this forum i would have learned by trial and error and probably would have made a few rookie mistakes. Just want to say thanks to you guys. Well with any luck i should be able to light it up today or tomorrow and hopefully will have no trouble. I am losing sleep over this freakin truck!
