Technical SBC induction engineering /moroso valve covers

I scored a never used set of Induction Engieering /Moroso small block chevy valve covers at the local swap meet part number E1000-111. I have been looking for a set of these for years, and I used to sell them at a local speed shop back in the day. Of course, there were no directions, Is anyone running these? it looks like there is a groove for an o ring under the polished lids, what do you use to seal the tops? And, What type of breather /PCV system are you running?

 

I’ve never bought it but you should be able to find o ring stock at industrial supply houses. You buy the diameter you need and cut and fit to length.

 

Could use a thin , neat bead of silicone as well ..

I found 2mm cord o-ring stock that worked awesome, and had the covers machined for pcv/ breather grommets!
