I`m torquing heads on a 140 tomorrow and have no manual and no idea...

A 13/16" Deep Socket and 9/16" Socket is needed.[/center]
HEADNUTS – ORIGINAL STYLE:
Used ONLY on Upper Head Studs These have the original style built-in “collar”, (just a flat washer under a regular nut is not suggested). Our head nuts are heat treated & have been tested to over 55 ft/lb., however, they should not be reused after the engine is run & the nuts removed. Head nuts and rocker studs should only be torqued 32-34 ft/lb. For all Corvairs. 12 needed to do two (2) heads.

CHROME ACORN NUTS: Install after the headnuts to keep the ends of the studs from rusting (for upper studs).

It seems the current consensus is to go 30 ft/lbs.

Yes 30 is generally used by most people but some report good results with 25.
