Golly. You're gonna need to tear down and do the LIM gasket... at which point you may as well be doing a cam. Though, it seems to me like you might just want to go with the 1.9" rockers route instead of worrying about the cam.

And skip the 180* stat until you find it's necessary.
K&N cones are pain in the ass because they get oil all over the MAF. Get a dry-flow filter. They're half the price.
You'll be happier with poly upper engine mounts than just a "dogbone flip." Maybe solid rubber lower engine mount and trans mount.
