Can anyone throw some thoughts on the specs and sequence for valve cover bolts on 1970 Olds with 455? Also, I glued the cork gaskets with some 3M weatherstripping adhesive around covers, but no sealant to the head's surface. Is this okay or do I need to add sealant? Thanks.

 

Don't put any sealant on the head side. Torque is 7#s, I just snug and go another 1/4 - 1/2 turn. Start in center and work your way out alternating from bottom to top.

 

Thanks a lot Olds.

 

And next week re-tighten them again.

 

Ok. I see ft/pounds and in/pounds wrenches. Which torque wrench should I pick? Thanks again.

Here it stands. 7 ft lbs for valvecovers.

 

Thanks a lot. I successfully spec bolted the covers.
