What size are the 6 or 8 bolts that hold down the cyl head. I tried 12-13mm but non seem to work. 12 to small- 13 to big, and 11 just seems to slip off. Need to remove head by tomorrow to re-tap #2 for spark plug, and also install my new head studs.

 

You using 12pt sockets?

 

No the first couple were regular. Guess i gota switch huh.
