Jan 1st, I don't even have a y-pipe for it yet!  I just bought the headers while they were still at a great price.  I still need to remove the rest of the cat y-pipe before I can install the headers.  But the old stuff is off and out of the way.  Anybody have thoughts on the best gaskets to use?  I forget which brand I used on the 68 but they held up good.  I'll eventually go with dual cats on the y-pipe but I'll just run an off-road y-pipe to get it back on the road.  Man, it's so much fun working on a car this time of the year!
