I am fixing an intake manifold leak... and right now I have the manifold and the valley pan off.

There was no gaskets installed, just a valley pan. FelPro says I should install gaskets, then the valley pan, then the 2nd pair of gaskets.

But what i really want to know if is, if the poower is way down, how can I tell if my cam is wiped?

Or....How can I tell if timing chain is stretched.... or the previous owner of the 440 didnt dial in the cam right?

thnx
John
