I don't like the KB 400 piston ... someone is going to ask why , because I just do not , I don't really like any KB hyper , but it's not my engine ...

I would get 516's and a flat top , either the speedpro or KB since you are on a budget and use the .021 steel shim head gasket .

The paint in the valley , as long as the guy cleaned it real good and it sticks and doesn't peel off ...
