Formula to shave pistons to reduce compression ??

Brooks James said
Huge snafu the weisco piston 5022h6 was discontinued 5 yrs ago. . I’ve called around/internet no one has any. Even called uk and s. Africa, one guy I called said that weisco would do a special order min 4 pistons. They are
400 plus. Néw good rings 150.
I can get an eagle all forged kit balanced for 1600. I’m thinking that this is the way I’m going to go.

I am lost here, you dont have the pistons and you wanted to have them milled to create some dreamed up static CR? What did I miss?
Just remember when you do things "the cheapest way possible" when building an engine and than you hit it with a bottle the net result normally ends up to be a big steaming bag of crap.
