With everything removed from 2511 I intend to mill all four mounting faces of the two aluminum engine mount assemblies.
While I will rely on my machinist's recommendation I see no reason why each of the four faces cannot be shaved by at least one 16th of an inch.
Mike Drew's blue thunder assembly fit OK until he replaced his rubber engine mount biscuits, showing that every fraction of an inch can be of value in the overall height reducing efforts.
I will update this post with the observed height reduction once the milling is finished.

Larry, there's considerably more than 1/16" to be had just by how much you compress the rubber engine isolator. I would think you could easily shave 1/4" off the lower ones. As far as milling the mounts, Jack DeRyke cut and sectioned his mounts and dropped the entire engine/TA assy by at least an inch IIRC. -That's a hole inch and a lower CG, and yes the pan may protrude below the frame rails. Not sure of your ride height but if you really think you're at risk of bottoming your chassis, bolt a skid plate over it. There are a few other things that will need to be potentially attended to but you gain a lot of height. Search Jack's thread on the subject.
Lastly, if you mill the carb pad on a slanted intake, be advised the studs are still angled. If you're only mounting the thickness of a carb flange it's not much of a problem but if you ever decide to put any significant height spacer on the intake it can be. While it's in the mill, I always redrill the holes perpendicular to the pad and install threaded inserts. Even though you're looking to pick up some height, you might be surprised how sensitive your engine performance can be to that carb spacer and even the style of spacer. Ask Dave and Dan what they typically see.....20-30HP with my combo.
Best,
