RW> I'm going to swap out the aluminum 1.6:1 shaft/roller rockers on the 56
RW> for 1.5:1 ball/roller rockers, with new pushrods. I'm doing this because
RW> the 'tall' valve covers require that I remove the alternator and air
RW> compressor from the engine to get the covers off (I'd like to check the
RW> lash every so often). The new rockers allow me to use stock height valve
RW> covers, which will clear the obstruction made by the AC bracket, which is
RW> bolted behind the alternator bracket. The label on the gasket box says
RW> that they're 'molded rubber w/steel shim core'. I always glue the gaskets
RW> to the valve cover, so they'll stay in place when I R&R the covers. The
RW> rubber on these gaskets has the consistency of the rubber on racing
RW> slicks, very sticky. That and the steel shim should make them seal pretty
RW> good on the head w/o glueing them down.
 
Don't forget to wash your hands!  I'm now wondering what kind of engine the
2000 Merc has in it and if it's anything like the one I have, which is a
royal pain to change the spark plugs on.
