.010 sounds about right. :-)
I would have the deck resurfaced another.010 so you can get a good quench area going for you,this has less tendancy to detonate.
I ran 12.to 1 compression ratio , 220 PSI cranking compression It did not detonate w/91 or 92 octane. Mainly because I had a positive deck of .002 to .003 pistons coming out of the hole.
Goodluck @ the machine shop.
