Need quick help with plenum spacer mod
 

The directions are vague, but should I reinstall the gasket that goes on the lower intake manifold collector? You know... The gasket piece that has the gold collector cover attached to it??

For the motordyne spacer the instructions say that you can either leave the oem gasket there or take it out. They say it should seal either way. They suggest removing it though.. I did when I did mine but some people like to leave it to make it easier to return to stock.

Remove the stock gasket since the spacer's gaskets are already applied to it.
