X-Head Porting....

DD, for the time & effort you are going to end up with from the porting experience, you are not going to gain much on your street car. I have run ported heads on street cars, just because I already had them & not seen much if any difference. Porting heads for a race car is a different ball game entirely, it is to gain the last little bit of HP & to help the engine breath more efficiently. If it were my street car, I'd run the X heads unmolested & save your nickles & dimes to acquire aluminum heads as being suggested to you. No one is going to see or know that the heads are ported. The only person who will know for sure is you, I'd put my time & energy into other areas of the car. Most people who have never done any porting end up with one head partially done & the other head untouched, sitting in a dark area of their garage. I've ported one set of heads & will never try it again, I ponyed up the money & let the experts handle all of the grinding dust. I now have a set of Edelbock & Speed Master aluminum heads to run on my race engines. JMHO
