Any thoughts on this port job?

Bought a cr5 engine recently for an AF project. Took a look inside the intake and exhaust ports and this is what I found. I'm curious if this kind of port work is going to kill my bottom end. It's for a trail bike so I don't want an all top end engine.

Oh and I know the piston is cracked. This engine is getting a full rebuild so I'm not worried about it.

Hard to tell really. The intake side has the ceilings of the aux ports tapered up which I don't like. The angle from the walls to the piston are done well. Exhaust side is sketchy

Send the top end to Roostie... You won't be disappointed...
