'06 Quicksilver Z06

Welcome aboard friends.

And a strange coincidence as it were.

With the addition of forum member LT1Pat, the number goes to "306".

Rhymes with "Z06".

And at the same time that forum member "ZedNought6" posts up.

And so it is, that the "306" member has PRC heads.

A good omen for those who are partial to those heads.

The most I would want to put down on the Z would be 600-650 to the wheels. I won't go FI route on the Z, that's what my G8 is for. I'm looking for the best option for the price and for my application. Judging from this thread, SS valve route would be the BEST option.

propain

Again, you continue to say its the best option but fail to qualify it.

Please do.

My friends;

I gave us all ample time and space to debate over the last day or so, and I myself may have participated.

We all managed to have a mad minute and get a few things off of each of our respective chests, and make points that we perhaps had not been able to make in the past as a result of the acquisition of new information, and the introduction of new parts. The new Ferrea valves come to mind.

However again, it is with utmost respect, and the respect that I have for my fellow forum members, and the respect that they deserve, even those with whom I sometimes disagree, that I have to ask that we move the actual "debate" portion of this matter outside of this thread at this time, and allow the thread to continue along it's intended course.

Thank you again, for your assistance, and co operation in this matter.

Point taken

Best is merely dependent on what the person would want to get out of it. So if the form fits it's function, and judging from this thread, it clearly does. So yes it is the BEST option for me, because I need it to do what's intended. What would your definition or qualification for "BEST" would be?

VetteVinnie

Best does not mean the only solution that was available at the time. We've since received two more alternatives, titanium and Ferrea hollow stems.

And I think the lighter the valve, the better. So solid SS is hardly the best option currently available.

Rupert pupkin

Which is true, there are different options. As long as there's a solution, then all the forum members can decide whichever route they want to make. I have done my research, and contacted 5 multiple speed shops and all of them had recommended going this route.

Continue on Quick.

And 9 out out of 10 doctors surveyed recommended chewing Trident. The key thing to note is "doctors surveyed". How many were surveyed? Because my dentist flat out does not recommended any gum chewing at all.

You forgot to delete the "5" when you wrote multiple. There are literally hundreds if not thousands of speed shops in the country. One of the most reputable shops, the one that built the engines for the C5R and whose head design was the basis for the newer generation LS engines, recommends otherwise.

Those other speed shops had no alternatives for a long time, so why would they recommend something they haven't tried?

Put me down as another SS exhaust valve user. I bought the car in October and took the car to Synergy Motorsports to have them do the wiggle test. Then, before they got started I called Rick and told him to just go ahead and pull the heads to rebuild them. So, they pulled them, sent them to where ever they send them, had new guides and valves installed, no head work. Got the car back, and man what a difference.

Car is all stock except a drop in K&N filter and some tuning.

#'s before tune were 453hp@5895 437tq@5005
#'s after tune were 490hp@5929 472tq@5051

Done.

Feels good to put this matter behind you, doesn't it?

What year is your car BTW?

Thanks

Did they check the guides at all to see if they were out of spec after they got them off? Or you didn't even want to know?

chetly

car is an '07 with 62k miles.

It does feel better having them done. Like others, I can afford the $1250 for the head work, but not the $15,000 for a new motor.

I didn't bother having them check the clearances. I did ask if the guys they send em to checked. His response was, they used to check just to see but after getting so many that were bad, they stopped checking and just went to work.

'06 Quicksilver Z06

Understandable.

With 62K miles on them, probably not even worth the time or effort to check 'em.

propain

Checking is simply a waste of time if you already have them doing the job and therefor a waste of money for them. Of course they would not want to.

07 with 62K miles I would said you were probably fine but whatever helps you sleep at night.

TT32VGT

got 3k miles or so on my ss valves(wcch st2-stock compression)
making 615rwhp/565rwtq(all motor) and have made prob30 passes.. everything great..

Dirty Howie

Local racing buddy is having Richard add SS exhaust valves to his stock LS7 after having guide clearances over .005, failing the wiggle test badly. He had less than 20K miles.

I will try and get him to post up here.

I'm waiting on VR/WCCH Stage 2 to be shipped out with solid stainless exhaust valves and doing a cam swap. I am the second owner 2006 with 19k.

Evolution-ary

Sounds like you mean me Howie ... will post up with complete details as soon as I get them... Was out of town last month, and as you know, was on the fence on which way to go once I got the warranty replaced heads, but finally went the SS route with Richard at WCCH ... will follow up shortly with all info, slated to get car back Weds or so.

2007, 19k miles... valves were Way IN SPEC some 7 months and 3k miles/5 track days ago Figured I should check again after Mike's blown motor at ACS! Glad I did!
