Thank you guys, I would prefer not put another gasket back in but
looks like I have no choice. Will use the "13" bolts this time.
The nut idea is a good one if I can just thread one on then either
tack weld on the inside or use some industrial strength glue on
the thread it might do it.
I bought a durapro graphlex with stainless fire rings as I thought
it would be a good investment if I keep re-tightening every 10K km.
I must make sure I replace all my stock head bolts with lucky 13.
