Pan gaskets... What do you guys recommend? Cork? Rubber? Fiber? 
Right now I'm using rubber gasket w/ silicon copper gasket and mine doesn't quite have the seal. I'm trying to see if there are better options out there.

I use the gm plastic gasket with the rubber oring around it and torque limiting rings around the bolt holes, reused it several times and it still doesn't leak or even weep oil.
Rubber and silicone only work if the surfaces are 100% oil free. Cork works sometimes but usually weeps.

Where did you get this special gasket? I've never heard of it. Dealer?
What type of trans are we talking about here. I use a fibre gasket for our 4l60e transmissions with a good/new factory pan. With a 4l80e I will use the oem reusable gasket with the factory pan. With aftermarket pans I will use a fibre gasket. Always make sure that your pan perfectly flat and always make sure not to over torque it. Vince

So I'll be buying new gasket and wondering if any of you fellas can help me out where and what to buy a BETTER one than I have been using.
We use the fibre one as I stated above. If you were close to us I would just say stop by the shop. If you have a Chevy dealer near you I would go there. The gasket they will sell you is very similar to what I use. It will be a black fibre gasket. When you have the pan down take a straight edge and run it along the bolt holes lengthwise. I find that the pan in your cars always seem to be tweaked where the cable bracket bolts to the pan. We do sell new pans if you need one. If need be give me a call. Vince

Vince is all over it. I had the o ring molded gasket from GM on my 4l80 with the stock pan and it worked fine. As soon as I switched to a deep pan and used the o rin molded gasket it leaked. Had to switch to the rubber gasket.
