  • HiYa Mister Douglas-
    Everyone seems to be going with head bolts these days. Here's a 7/16-14 x 7/16-20 x 3.00 stud, Grade 8, from SUMMIT RACING. It was the first place I looked so there may be others; allenfasteners for one. Note length is 3". OEM specifies 3 at 2.9" and 15 at 2.78" so if you must, grind off the 7/16-20 end that accepts the hex nut. Use an old one to compare with. Torque is different for nuts and bolts. The UNC (coarse) end, 7/16-14 always goes into cast iron. The UNF (fine) end, 7/16-20 accepts the hex nut. LINK for studs below, LINK for hex nuts listed in text. Hope this helps you.

  • The three longer studs were used where extra thread length was needed to attach the wiring tube to the top of the engine with a second nut. Check your cylinder head thickness before you buy bolts or studs. Some replacement heads are thicker castings. Leaving studs long can be a problem when it comes time to change spark plugs. Those threaded studs sticking up will do a number on your knuckles.
