Port and Polish anyone?
I'm going to assume right away that everyone will think that I'm an idiot for offering, but I will perform a mild port and polish on your head for $150.00. Reasons people will think this is a dumb idea:
1. They think they know everythign.
2. They've never done it themselves.
3. They think they know the process I follow.
4. They don't want me to make a little extra cash for school.
Let me tell ya what I can do for you.
A port and polish job is expensive mainly because it's a very time consuming procedure. A good job can take between 10 and 12 hours and is very meticulous. The reason I'm offering my services as cheap as I am is because 1. I could use the $$ for school, and 2. I enjoy doing it.
I'll take ya through it step by step.
On a simple port and polish, I'll start by running your head through a parts cleaner to remove any relatively loose debris. I'll use plastic bristle bottle brushes to remove as much carbon build up as possible before jumping in with the die grinder. The bath is followed by a thorough cleaning of the intake ports of the head. A good cleaning is as far as I go unless I'm match porting to your intake. The reason for this is because the intake side of your head is very picky about how the air flows. Removing too much material can have adverse effects on performance. Nevertheless, a good cleaning is always in order. After cleaning/match porting, I will take to the exhaust side of the head. After cleaning the remaining carbon build-up, I will follow with a mild stone to remove harsh imperfections in the ports of the head. I only remove a slight amount of material through the process. I will follow the mild stone with a polishing stone impregnated with fine emery abrasive. It brings out a great finish in aluminum. It is followed by a 120 or finer grit flap wheel and finished with a felt polishing wheel and polishing compound. It brings out a great near mirror finish on the aluminum.
This process offers greater air and exhaust flow, and helps prevent carbon build-up in the future.
If you have any other questions, please feel free to ask me, I'll tell ya whatever you feel you need to know!

No offense but you seem very defensive about your "work".
To me it sounds like your offering to run someones head through a parts cleaner and then port match the head for $150 not a real P&P. Just my .0002 cents though.

The only reason I'm defensive on this forum, is because ya can't say two words without someone picking you apart, ya know what I mean? The people who do speak up think they know shit, and 9 times outta 10, they don't......
Anyways, if you would have actually read the post, you'd realize that it's not just match porting.... If you can give a great detailed definition of port and polish, I'd love to hear it...

Anyways, good luck....and you may have better luck if you outline your work then answer questions as they arise instead of the other way around.

Are you aware that a mirror finish is not neccessarily a good thing in a port and polish? It promotes laminar flow.
