While I don't go as far as Woodz with the situation I do at least re-torque everything aluminum after a few heat cycles and again after 1000 miles. He is correct that you do need to break each fastner loose and re-torque in the correct order/pattern. I've just never thought it was required after 1000 miles or so.

The Chevys I've run in the past always had the intake bolts work loose in those first few heat cycles.

Most every car and light duty truck out there now has an aluminum intake and most (especially on V6 or V8's) have some sort of leak occur later on due to this issue.
