Mine wasnt too bad thank god. Castrol Syntec was being used and the car itself was taken care of by the previous owner.

Im glad that we went with the porting though. I dont know what brough it on, but Bill made a call and before you know it he had a dremmel on it. It took a little more than an hour to do both sides before we cleaned it up, and I do notice a difference.

Im a VERY happy man!!

I would also like to thank Wren for being on the other end of the support line. I really appreciate it!!

Well not exactly. You need a micrometer to measure, and measure, and well, more measuring. You also have to be carefull on the inside while grinding it down. You have to have a feel for it. I didnt do any of it, but I was watching VERY closely.

Bill did an AWESOME job as you can see from the pics.

The funny thing is, I do have a micrometer. So, maybe if you can give me the measurements, I can give it a shot on a practice peice of metal or something, idk. How much power do you think you gained??

Heres something from a page I found on the net about porting:

Quote:
Nearly every performance car guy has made an intake swap in the quest for better breathing and improved performance. The problem is that after spending a couple of hours making the swap, sometimes little if any gain is achieved. You scratch your head, yell at the dog, and are downright mad about investing your good time and money for relatively no performance gain. You wonder why.

Mismatch | Back To Top
The answer: the port openings at the end of the runners on the intake manifold do not match up to the port openings on the cylinder head. The resulting mismatch causes congestion of the air/fuel mixture as it travels toward the intake valve. This snarl-up slows down the velocity of the airflow.

Well, with a little planning, the proper tools, and some patience, the average do-it-yourselfer can clear up this congestion by port matching (gasket match) the intake manifold. This port/gasket matching is just what the doctor ordered to enable your engine to better breath!
Its not a HUGE difference, but you do notice it and IMO its well worth the time to do.
