Guys, I was not goign to say anything about this until I had it installed. Once I saw it, I just could not wait. I have to show you the before and after as its pretty funny. Before is easy to spot. It was thrashed. Still a decent value even though I did have to buy a new powervalve for it. It is better than changing a good 250 cylinder. Obviously, the second pic is Erics work.....LOL I dont know if the picture will do it justice. Its the same color as an 06 stock cylinder, now. You can see that a ton of work has been done to all of the ports. They are semi-smooth, and sharp on the edges. Slightly scary looking as I can see this will make some serious power. I've seen the work the other companies turn out and this looks much better. I also took a picture of the damaged powervalve. I dont know if this is normal or not. The cylinder I bought was a 2003 and appeared to have quite a bit of run time on it.
