There are two hyper pistons Speed Pro (Federal Mogul) makes. P/n 405p which has a compression height of 1.576 with a 0.070" recess and typically yields 8:1 or so compression and H116CP which has a compression height of 1.66 with 5cc valve reliefs. It will give 9.5 to 10:1 depending on head volume. This is the one I used. I have 10:1 compression and run 91 octane but can run 87 without too much issue. My engine made 397hp/435ft lbs with a mild hydraulic cam and Edelbrock heads. I didn't have to balance mine with this piston.
With factory heads it might require better fuel. Good luck with what you decide.
