Last Friday I was coming home on a nice curvy road having a good time. On the last turn just before my house I was in 3rd around 8000 rpm. I had to break a little to make the turn and I wanted one last good red line shift through 4th. Well I guess I hadn't slowed down as much as I thought and throwing it into 2nd caused some odd noise and loose of most power. 
I pulled over and let it idle and it's the worst ticking I've heard and I own a 91 3000gt vr-4. I knew that I had shifted way too early and over rev'ed the motor smacking the valves on the pistons. :sad: Live and learn ... it's entirely my own fault. I've driven manuals my entire life and never done something like this. They say that most accidents happen a few miles from your house. You get lazy and complacent ... and that allows you to make mistakes.
Well I just got the head off (with out pulling the motor) and I see that every intake valve has a nice shiny side to them and not exactly fitting the head very well. I would say I have 20 hours into this project so far. Examining the pistons and piston walls ... I don't see any problems. Each cylinder walls are clean with no scratches so I don't think I did any other damage.
I received a full new set of valves, springs, retainers and sleeves from MWR. I should be able to get the head to our local machine shop that does nothing but heads early next week.
I'll snap some pictures and post updates when they happen. I just figured I would share.
Good night!
