TTA# 130
The copper exhaust gaskets that fit the GN. Will they fit the TTA also? If not which exhaust gaskets are suggested?

I think that is where mine came from, I got the manifold gaskets elsewhere.

That is the ones I am talking about, exhaust manifold gaskets. According to highway stars they fit the GN and TTA. Just wanted to confirm because sometimes I've seen vendors list things wrong. Since the heads on the TTA are modified it because of the room didn't know if gaskets were different. So the ones from highway stars do fit and someone here has used them?

When I replaced my turbo I purchased all of the gaskets needed for the install from them. It worked for me. Or call them up and talk to them, Glenn will know for sure.

My exaust manifold gaskets were not purchased from highway stars.
They were put on while it was in the shop, I am not sure where they came from.

They are different from the GN ones. Heads and the headers are different on the TTA.
 
I've tried them all, even running nothing to running Hi temp copper RTV. The ones from here http://www.buickgn.com/gaskets.htm as Dvernst suggest are leaps and bounds better than ANYTHING out there.

Worth every penny and more that they cost. Do not over torque them !!!
 
Nice thread. Didn't know buickgn sold those gaskets for us.

I had the headers milled and using only hi-temp. So far so good.

Same here.. Headers were surfaced with a belt sander, and used copper rtv. I bought the gaskets, but wanted to try without them...
