Hi everyone, I got my Z06 a few months ago with 6500 miles on it. It was modded by the original owner before the heads debacle surfaced so they were never addressed. My car has a cam, supercharger, full exhaust, cooling upgrade, along with a list of other mods that support the extra power. It has 7400 miles on it now and about 6000 with the mods. I brought it in to the shop that did all the work on it originally and was very curious to know how my valves and guides look on an engine that produces over 600rwhp. My heads are due back form the machinist this week, and have been informed that my guides and valves looked quite well. No problems at all. I have noticed in the time I have owned it that it has no valvetrain noise, its very quiet. I have read how other owners are experiencing unusual valvetrain noise. Anyway, one head had an issue with core shift from the factory and the ports and one valve seat were not within the machinists spec, so that was taken care of. I now have solid stainless exhaust valves with bronze guides and has been cnc ported and milled. Hopefully it will be ready this week as it has been away for longer than I thought. Looking forward to seeing my new dyno numbers once its completed. I read some stories about some cars that had issues with as little aqs 5k miles so I wanted to share my situation. Oh, its a 2009 model. Can't wait to get it back, I'm missing it alot.

Congrats on the Z, why the mill on the heads on a supercharged car?
