Guest kaycee Posted December 18, 2011 Share Posted December 18, 2011 Here is the order for 1940-1954 straight eights from my Motors manual as per their picture of the head and tightening sequence: 20 19 18 15 14 10 22 23 26 27 30front 5 4 3 2 1 6 7 8 9 rear 21 17 16 13 12 11 24 25 28 29 Cylinder head bolts torque: 60 ft. lbs. in the order above after cleaning and oiling the bolts.Motors says to coat the head bolts with white lead and oil and tighten finger tight initially and then torque down in sequence above. I always retorqued bolts twice and once again after I ran the engine. Good luck, and have a great Christmas and New Year! kaycee Link to comment Share on other sites More sharing options...

Guest H1950 Posted December 18, 2011 Share Posted December 18, 2011 kaycee what is the white lead and where can you purchase it? What kind of oil does manual reccomend? Link to comment Share on other sites More sharing options...
Guest Krooser Posted December 18, 2011 Share Posted December 18, 2011 Forget the "white lead"... it's an obsolete lube used until it was banned from most countries. Machine shops used it on "live centers" while doing lathe work.Use regular 10W or a similar oil for lubrication... any motor oil will do. Be sure the threads are clean.

Guest Posted December 18, 2011 Share Posted December 18, 2011 Chase threads with a tap and die using WD40, then clean oil/rust residue with brake kleen, blow dry, add a thin coat of anti seize and install. The anti seize takes the place of the lead.------just use a very thin coatingDon Link to comment Share on other sites More sharing options...
