Different pistons would do it.
I think what is happening is an assumption was made that the factory compression "spec" was just a little high and that a few tweaks could bring it up to "spec".
In reality, the factory compression "spec" is a
lot higher than actual (~10.4:1 actual vs 11.3:1 factory).
I think one would need to ignore all the other dimensional specifications to modify cylinders/pistons/etc enough reach the factory compression "spec".
IMO, I don't think any racing body is going to accept a motor with 9 points higher compression (than a truly stock motor) as "stock".
