Its always a bit iffy on what will ping and what wont with all things being equal but many things being different.

If ya want a fussy motor when it comes to fuel just build a 11:1, if ya want to be safe and not worry shoot for 9.5.

Weather a W2 motor or X or J motor if you use the proper parts a real 9.5 motor can run very well.

The silly banter of 10.0 vs 9.5 ect isnt going to affect the end result power wise much at all.

Ive had a few on the edge of the fuel needed and thats when you find who sells good fuel and who sells not so good fuel but would of rather had .5 less and never have the worry or keeping that can of octane boost in the car.

HOWEVER... The web tell me your near 5000ft above sea level, if thats the case you might be ok.
