Complete kit:

Or you could just buy the flange gaskets from them & buy the header gaskets & bolts from any parts store:

I used Fel-Pro 1406 gaskets and ARP 3/8 Header Bolts

I bought some Edlebrock 2.5" Donut Gasket for Header/Y-pipe connections.

The stock gaskets work on pipe to cat/y-pipe, or they did on my 97.

95 black on gray leather z28 with odbII dualcats
Actually I believe that the 95 Dual Cat California cars were still OBD I, that is what was stated a while back when this discussion came up.

Also why won't the 1406s work on both sides?

I used ARP 1" header bolts, you can get those and the Felpro #1406 gaskets from www.summitracing.com thats where I got mine.

Arp 3/8 bolts are worth thier weight in gold in my opinion. They were so much easier to work with than standard header bolts and only about 6 dollars more.

Not to sound like an *** or anything, but what are you talking about on the 1406 gaskets?? I used the set with no problem at all. That, and I got a set of header bolts from autozone for $3.99. Just retorque after the engine warms up and cools down once. Get some high temp RTV and put a little on the 1406 gaskets so they won't blow out(cheap insurance). I dont' know about the gaskets that go in between the headers and Y-pipe though.
