Okay I hope I'm just going crazy. I bought some e7's to replace my e6's. I've been working on this motor for a few months, and forgotten a few small details. I have done everything on this motor (including the actual machine-work.) And now I'm putting on the heads. I put the driver's side head on (motor on stand, facing it, on your right side.) The spark plug holes are facing back, away from the front of the engine. I put the other head on, and WTF the spark plug holes are facing me! So is that normal??! I've changed spark plugs on that car a few times, but I can't for the life of me remember if the passanger side plugs were facing me! Do I have a normal pair of heads or two off the same side? AAHH!!
