nhcamper Posted June 2, 2008 Share Posted June 2, 2008 Hi, Can anyone out there give me the torque spec. for the 20R head bolt? I don't have a manual handy. I am doing the head gasket on a 77' Chinook. Thanks, Tim Quote Link to comment Share on other sites More sharing options...
rickcedar Posted June 3, 2008 Share Posted June 3, 2008 The manual that I have shows for a 1975-77 20R. Cylinder head bolts (52.1-63.7) Ft.Lbs. 1978 20R (52-64)Ft.Lbs. Hope the info helps. Quote Link to comment Share on other sites More sharing options...
nhcamper Posted June 3, 2008 Author Share Posted June 3, 2008 Thanks for the spec. I have it all apart, ready to send the head out to be checked. I hope it goes back together as easy as it came apart!!! Quote Link to comment Share on other sites More sharing options...
