Hi. I have my valve covers off for a general engine bay refurb. I'll be replacing the old decrepit hardened valve cover gaskets with new rubber gaskets, which should help reduce the oil leakage I've been having at the valve covers, but I've seen a FEW products that claim to help reduce leakage even more.
1 - One is the valve cover hold-down bracket which you put at the fastening bolts for the valve cover. It's supposed to spread the pressure of the fastener over a greater area for even distribution.

2. Another is a very thick gasket available from JEGS. It's rubber, but thicker than the more standard rubber gaskets I bought (Fel Pro.)

3. Also, studs rather than bolts have been promoted to help leaks.
Do any of these products work? Do you have alternate suggestions? Thanks
