Heads are done, engine starts, ready to put the exhaust back together
on my 2.1.

At the big flange between the cat and the manifold pipe, there is a
iron ring gasket, and three bolts go through the mating flanges. When I
removed the bolts, there were a number of washers and spacers between
the flanges that look like they were there for a purpose.

Should they go back in the way they came out, throw them in the trash,
secret procedure???

Thanks,

Jim
