Exhaust Manifold Gasket

[TeZZaP]

I have just taken off my inlet and Exhaust Manifolds. According to the book, early one's should have an all-in-one gasket, where as later ones should have a gasket on each of the inlets, with the exhaust bare metal to metal...

Mine had both the full gasket AND the two inlet gaskets fitted; would there have been a reason for fitting both early AND later style gaskets, or do you think it was just plan wrong! And should I fit just one type, or replace it as I found it? What do you guys think?

I do not think there is a lot to choose between the two types of gasket, but I have used the one piece one. But I would not use both!

I am guessing that both were used because the gasket set included both, so the person fitting it thought they should both be used.

The secret to success in installing the manifolds is to gradually tighten both the studs into the head and the studs holding the two manifolds together so that neither is holding the other out of alignment. start by tightening the nuts holding the two manifolds together just enough to take up the slack, but still allow them to move, then bolt to the head, but again leaving the nuts loose enough to allow slight movement, then tighten the first set a bit more, then back to the second lot, and finally torque them.
