Polishing head on 4000q

Polishing various parts of my 4kq engine for +25hp?

The head gasket on my 4kQ is gently leaking. I work with a mechanic in
Denver who says he can pull the head and: Grind the valves, polish intake
and exhaust manifold, etc for $600 plus his labor. I'll probably have him
do the timing belt and water pump while the engine's aprt. He thinks doing
the polishing/porting etc. will produce about 25 more horses, which would
be nice for less than a grand total. Anybody have any thoughts on this? I
quite like the mechanic and think he's done good work, it just seems like
kind of a large gain for the money (not that I want to spend more, can't!).
