Man would I love to have these but I have to ask and please pardon my ignorance, are they smog legal? I live in CA and if I remember correctly I need exhaust crossover for EGR function. Correct?

Tuned Performance

iTrader: (92)

Yes, unfortunately for ca emission you would need a corvette intake or aftermarket base tuned port injection egr rear feed. Dyno don has made headers for these heads in thirdgens with the egr feed.

U do any trades? I have lots of guns.

-=Z28=-

iTrader: (3)

not to be a jerk... but it looks like in the one pic, the gasket surface has a gnarly ding in it... how bad is it?

Tuned Performance

iTrader: (92)

Head gasket ?
Sorry I don't need any guns, I could use some concrete though !

-=Z28=-

iTrader: (3)

no, on the head its self. on the gasket surface by the valve bowl. maybe its the pic. looks like a ding like it got set on something hard.

Tuned Performance

iTrader: (92)

The only surface I can see that isn't machined perfect is post 9 picture 5.
The valve cover gasket surface 1/4 of the outside edge looks like it's gouged or scraped.
I didn't even see that as a concern.

-=Z28=-

iTrader: (3)

3rd and 4th pic. In the 4th pic the valve stem points right at it. without machining those flat, that ding will prevent the head from sealing. Like I said, Im not trying to be a jerk, But I see that ding as a huge deal. Especially dealing with aluminum and its expansion rate vs cast/iron/steel. Must be perfectly flat, or you will have sealing issues. Is price negotiable?

Tuned Performance

iTrader: (92)

Price is negotiable, I realy don't want to drop it to much yet. I do have a rebuilt set aswell
