Ayuh,.... Donno, but seems like it's some light number like that,...

They're 3/8" studs,...
I run 'em in/up Snug, 'n torque to 'bout 30/ 35ft.lbs. per a calibrated elbow...

Never had a leak, or distortion yet...

The manifold to head is 20/26 as noted. The manifold gaskets were 12/18 ft.lbs. with the old style gaskets. The new metal shim gaskets are 25/29 ft.lbs using the new procedures shown in the instructions that come with the gaskets.
