Motor help needed

I have a 65, 273 motor with 8.8 to 1 pistons in it with solid lifters. I am looking to put the 10.5 to 1 pistons in it. Will there be valve to piston problems or will the gap be large enough. I believe the heads are a stock variety of the 1965 273 2 barrel carb car.
Does anyone have any experience with this combo ???

Any help would be appreciated.
