this is a slight downgrade but id have to change a few things or is it not worth the effort?

Would need to use EF timing cover for CAS mount.
Jimmy something up to mount knock sensor on block, or not use it, although some people have theorised this may have a negative effect on timing maps. Don't know myself.
Swap dizzy for cam angle sensor obviously.

Engine wise, ED compression is lower (piston has larger dish), less counterweights on crank (EF better balanced), different head casting if you are using top end.
