14 bolts hold the Head on the engine.
How deep are the 14 holes in the block
(and how deep is the 7/16-14 thread)?
Additional : Did you ever drill any deeper??
Thank you very much
Best regards
Christoph
The head is still on the engine, but i know that a
heli-coil (bolt8, which holds the ignition-cable) did
let go while i retorqued to 55 ft-lbs
