Yes 10:1 will be tough. i have been down this road many times. I would seek out better gasoline if you want to go that route with that compression. You have to be on point with tuning but even then you cant set the timing to where it would be optimal for the engine to run like it should. I would drop it down to 9:1 with custom pistons since there is really no choice with an off the shelf piston.
