I have ported by exhaust manifold with a die grinder, that should do it for the porting part. I suppose even a dremel tool would work too if you wanted a super cheap way.

Standard Abrasives makes a kit for DIY Port and Polish. Their products are what we used when we used to offer ported and polished HF Style manifolds.

Here is a link to their PDF guide for Port and Polish

You can buy the kit they use at Summit Racing.

turn on the car and slowly pour a ten pound bag of playground sand in the intake. Don't get cheap sand tho, otherwise you'll need more like 20 pounds.
