First off, I just bought my C6Z about two weeks ago. Velocity Yellow(hence the name), under 40k miles in Pittsburgh PA. I'm active duty in Hampton Roads.

I'm planning a complete bolt on build, with top internals. I think I've gathered enough information from the years on what I want to do. This forum and you guys have so much experience in here, and lessons learned that it made it easy to make the decisions to get to 600 whp on a stock bottom and na.

Originally I wanted to go ECS or A&A centri supercharged, likely ECS due to location. Couldn't go wrong with either in my opinion, but then the guide rod and valvetrain issues with the LS7 made me paranoid. The engine sounds great, like a sewing machine, not super smooth. I plan to remove the valve covers next weekend for the wiggle test.

in the mean time, something I haven't been able to entirely find and easy answer on by searching. I believe it's a sub contracting issue from GM having somebody else machine the heads, and tolerance getting messed up there. However, have there been any correlations between the actual builders of the engine, and engines with dropped valves?

Just looking for some reassurance. This winter I'm going with AHP, and just rebuilding them. Only planning on driving the Z on nice sunny days, a little spirited driving, but I would hate to lose the motor when I've already got plans on a top end rebuild about 8 months down the road after I save a little more.

Huge thanks to all of you guys for all the information you've gathered here. Very happy to finally be an owner of a true piece of American History!

Wow, 31 years! Congrats, that's a great career. Thanks for your service as well.

Great choices for your kids, mine are all too young or I would gladly send them to boot camp haha... there's a lot of opportunity on the outside if guys truly apply themselves. You don't see it as much now, and the younger generation seems to have a sense of entitlement.

Gotta raise them right so they make enough money to buy dad that c8 zr1...
