Picking up some fresh ls6 heads, questions.
So I'm picking up some brand new ls6 heads with .650 lift springs and pushrods (assuming they're 7.400" but I'll check) next week to replace the 853s on the car. Getting a good deal or else I'd save for something better. But my question is, should I get them milled, ported, or what? I will be getting a custom cam spec'd out as well.
