Don't know what gains people have gotten when THEY'RE the ones porting, but if you have lots of experience and know what you're doing, then you should see fairly decent gains from it. The majority of us have someone like Lloyd Elliot do it 
(Me not included in that, but if I had the money I'd send mine to him)

the valve job and fitting bigger valves would be the worst part i would imagine.
i would give the intake a shot for sure if you are going to pull it off. i dont think you would see enough of a gain relative to the amount of work to pull the intake to make it worth it without porting the heads.

Has he done LT1 heads?? If yes and has a good rep then I would say its a good deal.
I had LE do mine since you know it will flow great!!! My buddy paid a place call E&R racing 5k to PP heads mild cam and a tune and only picked up 4 tenths.
Make sure they Do LT1 heads and ask for dyno numbers of happy customers.

you can almost always put bigger valves in and improve flow..especially the valves with the cut underside which basically makes more room for the air to flow throught the throat. and like said.. make sure he is a reputable guy..anybody can port .. but you have to know where and how to increase airflow and not disturb it.

just by taking some off here and there doesnt mean it will perform better. it could easily make it worse or just about the same, potentially wasting money for no gain.
i would leave it to a pro (unless the guy you know has done alot of LT1 heads). AI or LE seem to be popular, even though i havent had any experiance with either.
AFR also manufactures new heads right out of the box.
i say go for the intake though and use common sense and polish it up nicely.
