one of my pistons got damaged some how by the piston ring cleaner, and im thinking about buying a whole set of pistons, but the ones i see for around $100 for my 455 are lower compression, and mine came stock with higher compression. what would i need to make this change work with the other one? and if i just leave everything else the same way but lower compression pistons what power increase or decrease will i notice?
thanks!

 

What is the compression height of the pistons you have now?
