Okay-
I am having issues with keeping the acorn nuts on my head tight (joke in there somewhere!). Anyway what are you guys using to keep them tightened to spec. I don't even have 2 hours on the top end yet and I am getting loose nuts! Have torqued them several times already.  I noticed coolant leaking so I checked them and most were loose. The top end was re-done by HPR so it is an o-ringed head. Any suggestions.
Thanks

Did you find out what was making your head nuts get loose?
