I'm just finishing mine up. Same thing.1936 21 stud cast iron heads.This is what I used/did: I ordered "Best" gaskets from Napa.Part #507 G (Ford V-8 221 1932-1938 [21 stud]truck 1932-1937).The parts house guys and the machine shop guys said "No sealant" with this type gasket (Graph Tite).I went with Ol Ron's suggestion, 45 lbs. torque in increments of 5 lbs (I think he recommended 10 Lbs.) This morning I did the 5th re-torque and one or two of the nuts moved just a little so I'll warm it up again,let it sit overnight and do it again.I took the heads to the machine shop to have them checked.They were out a little so they surfaced them for me.Surfacing was @$90 and gaskets were @ $110.So far,so good.No leaks.The machine shop checked the heads by laying a straight edge on the surface from end to end and slipped a feeler gauge between the straight edge and the head surface....it was out about .007.I didn't seem like much to me but I had them surfaced anyway.I'm not much of a mechanic....just telling you what I did. Good luck. Gene
