I know this has prolly been asked and answered a few hundred times in here, but my search didn’t specifically answer my problem. Rocket Racing valve covers and speedmaster aluminum heads. Can’t for the life of me get a good seal and i am certain it’s me. I’ve used ultra seal, edelbrock and the once from rocket racing still get seeps, drips, etc.
Try the Cometic gaskets, a copy of the discontinued Felpro Permadry with a rigid carrier and rubber sealing beads. I had issues with the cheap chrome valve covers and the Edelbrock version of the MT aluminum valve covers. I had either use straight RTV or the Permadry gaskets. I have minor seepage with the Rocket Racing gaskets on factory valve covers. I still had leaking with Permadry and the Edelbrock aluminum valve covers. I used Optimum Grey on the valve cover side, problem fixed. It is much less visible than other RTV and very strong. Check both with a straight edge, maybe one or both surfaces are warped, good luck.

Above. Would check both sides with straight edge. On a side note! Is that the new Edelbrock vrs-4150 Carb?? If so what CFM and how you like it?
Thanks for the reply’s, good advice and well give them a try.
highwaystar 442 - this is the new edelbrock carb and i love it. I am officially done with Holley products, had 2 quick fuel carbs that were nothing but problems. Cutlassfi mention the edelbrock to me as he has built a few engines for me. I bought it and out of the box what a difference. Very little tuning, but super easy. No choke on it, but i live in FL so no biggie. It’s the 850 cfm
I got the cometic and used a little 3m black on the valve cover side and dry to the head. Problem solved. They are 100% dry. I like how they compress and give a good tight feel.
