Milling 5.3 heads

I'm replacing my stock 5.3 heads with new ones, how much can I have them shaved before I have issues? This is all on a 5.3 99 truck engine.

We've milled heads as much as .045" without a manifold fit issue. I suppose youe could mill more, but you may run into some problems fitting the intake manifold.

Good luck,

Richard
