Another FYI for new guys at this. Beware of the cylinder head cc's in the stock head to the new head. When making the move from iron to aluminum, the heat goes out of the chamber faster through aluminum. This is where you find the mention(s) of moving the compresion ratio up 1 pt. to recapture what is lost in the quicker heat transfer.
Those closed chambers are just begging for flat-top zero-deck pistons, which is what I'd recommend anyway.
