While I'm waiting for my block to come back from machining, I'm tearing down my heads and cleaning/replacing components. Still not convinced I'm reusing these heads yet though(E5AE). I noticed that the intake valve seals are the locking type (rubber w/ metal lock ring). The valve guides for the intake sides are also smaller in diameter as seen in the pic. I've noticed that the aftermarket variety "performance" valve seals require milling in order to use them. Are the valve guides typically the same outside diameter...meaning these have already been milled at some point?
