that does look like kinda a piss poor exhaust setup, theres a LOT of room to move the port ceiling up but you lose the water circulation above that port which would lead to more serious problems. I guess for a daily type driver engine all in all its not that bad.
Looks like some pocket porting would go a LONG way in improving the flow on the exhaust especially directly below the seat, some added duration couldnt hurt either. If I had one of them v-12s i'll bet I could live with its lack of power.
