early A body engine swap

Remember the "TABS" are for only the lift on the torque and those mounts appear to give you a 1/4 inch lift, so not to break the mount. I never used these, but looking at your photos, it appears you may be able to face the tabs towards the motor or front and not face the headers, rear.
Does the orientation of the mount affect the height where the engine will sit? Please check my previous photo: the issue I fear is that if the engine goes any higher, the header which curls under the frame rail, starts hitting the frame rail.
