Shim up the back 2x what it is now. That'll help. The engine doesn't need to be perfectly level. You'll be fine...

This is mine before I got rid of the OEM air filter. Raise the rear enough to plumb in an oil drain line. I didn't do this, and my oil drains onto the motor mount. I just clean up the mess and deal with it.

Put back the OEM engine mount. Set the engine in place and lineup the passenger side mounting holes. They should line up. Enlarge the drivers side holes as needed. The CCP kit uses billet aluminum blocks under the engine, utilizing the stock engine mount. The rear block is thicker than the front one, by maybe 2x.
