I just recently replaced the engine on my c6 z06 after dropping exhaust valve. I now want to do a heads a cam swap for more power. I wanted to do a cam only but i was told im better off changing the heads so i wont have the same problem. If you guys can give me some feedback on some options i can go with. My car is completely stock except for corsa axle back

If you went with all factory parts, there is nothing in stone that shows that the new setup is any more immune to the valve issue. Putting a cam in only seems to exacerbate the issue with the valves due to the higher stress on the valve train. At a minimum, i'd suggest springs, guides and exhaust valves for a cam install... but only my $.02

Doing work yourself or shop?

WCCH, PRC, AI seem to be top choice for heads. Cam depends on what you want and can live with. I would call Carlos@Vette-air and have him give you a cam. He has cams from baby unicorn to demon hellbeast rapist cams.

Damn, so you dropped a stock valve too???

What happened and when? Street or track? Any pics?

I'm glad I read this about head work not necessarily fixing the dropped valve problem. I was looking at doing a H/C set up to get to about 550 whp. I was looking at stock heads done WCCH Stage 2 at about 11.8 CR.

So would a Mast 285 LS7 head solve the dropped valve problem?
I just bought a bone-stock 2008 Z06 and it is a fun ride. My '08 C6 makes 825 whp thru a Power Glide (the one in my signature), but I haven't taken it out of the garage since I bought the Z06....it's too much fun rowing them gears.

I don't think you interpreted his statement correctly.

The worst thing to do seems to be to put a large cam in otherwise stock heads.

Building the heads with SS ex valves, dual springs, and bronze guides is necessary to go along with a bigger cam according to many experts. I even did this for my stock cam based on the advise of experts that I trust.

Ah, OK. I guess I'll keep WCCH on the table as a strong candidate for my H/C. Seems there are a lot of Z06s using WCCH Stage 2 heads.

Dirty Howie

Yes based on all the members who used him before me I decided to check him out about 1.5 years ago. He is local to me. So I actually went down to his shop and did a pictorial review. You can find it in this section of the Forum by searching. I wound up doing his recommended treatment for the heads and have recently had him port them too. So now they are Stage2. Again if you search you will see lots of video I post giving the heads and motor a good work out. Talk to Richard, you won't be disappointed

I think me and Howie are the only ones maybe on this board that have actually driven our cars after heads and cam setups over 10k miles on mine so far. So I think its a must to upgrade to better valves and springs... I'm on stock OEM guides instead of bronze...

I am taking the car to a local shop here in socal, i was actually trying to get all the parts i need for the h/c swap and taking them in just to get installed and tuned.

I hope your going to one of our Corvette Challenge sponsors.

And shoot me a PM when you want to come out and join us. Beginners are welcome

call Carlos he will hook you up with heads and a proven cam. Im installing a widow r cam and wcch from him.

Bronze guides, yes; but SS exhaust valves and dual springs are not necessary according to some other experts (i.e. Katech):

If Trickflow ever get's their shiit together, they have a new head coming out. Details are a bit obscure at this point. I love their proposed rocker mounting set up. I would never buy a cam without knowing the valve events. Stupid names mean nothing to me.

Maybe but there have been pictures that show inconsistency in the walls of the hollow stock titanium (sodium) filled valves. Ideally if there is little to no side loading you should be fine but the valves are just another POSSIBLE weak point that most choose to replace while they are in there. I went with mast heads, made great power and never worry when I beat on my car. Going the wcch route only saved me 300 bucks after buying my Mast heads and selling my stockers. No brained to me.
