The 340 Forged Piston Is So Heavy....

I'm thinking about taking some weight out, any instructions anywhere that will help as far as how much and where to cut? Thanks

I have a set of the trw 340 pistons new in the box. Would I use them on a real under the index killer setup, that would be no, But these can be used still to build an engine that could easily run .30 under the index.
