im not sure if i need to be putting money into these, anyone advise?

You want my personal experience and suggestion or the advice I'd give any clubber?

My front manifold went on dry..the same way the old one was. I reused the lead donuts for the crossover and then reused the thin metal strip gasket that I found on the rear manifold.

No leaks.

Can't re-use them. The compress with each application. They're cheap. Get new.

Bill...I think the different years have a different style..they weren't the compressing lead based type.

i re-used mine

Any leaks?

Maybe leaks are primarily an S1 thing?

no leaks.

Same here. All good

yea they looked pretty good, the new ones are $4.99, but have to be ordered

Put the old back on. If you have a leak..then deal with it.

So far.. no S2'* seem to have leaked on old gaskets yet.
