Compression Height

I just came across this forum and am enjoying the information. I like you have been unable to find piston specs. I have a 1960 Tbird with the 430 Lincoln motor option. The Tbird manual lists the compression ratio at 10.1. I have dismantled the engine for rebuild and measured the piston. The compression height is 2.005 inches from the pin center to top of piston. My pistons have a small wedge on the galley side. I am trying to find pistons with a flat or dished top and slightly lower compression height. I would like to lower the compression to approximately 9.5. This would make it easier to run on the gasoline we have today. If anyone has suggestions they would be greatly appreciated.
