I was planning on using the black permatex (
Henkel Loctite 598 RTV High Performance Silicone Gasket Maker Black 70 mL Tube ) ... want to try to keep it as stock as possible and it worked very well on my 92 camaro to not only seal up the valve covers, but glue the gaskets in place ( I had to double up for clearance due to double roller rocker arms )
