    Valve cover gaskets - cork or rubber?

    I installed these but both sides seem to the leaking at the back

    What gives? Is cork a better way to go? Any goop needed?

    If those are the neoprene (or similar) with steel core, never ever had one leak. Actually assembling a small block 347 with em right now.

    I think so yes. I snugged them up some more. Seem to be sealed now. Maybe I was just being a little light with the ratchet Usually I’m known to break stuff so trying to adopt a litter touch these days.

    Pressed steel covers or aluminum?
    If alum, go round n round until you feel them settle.
    If steel, suggest factory style spreader bars then tighten as above.

    I used Ford steel core rubber bead gaskets on my 89 with stock valve covers.
    They have to be over 25 years old and never leaked a drop so far.

    Hmmm, seems I’m just special. I’ll keep an eye on them. Seemed ok after a little drive last night.
