    I bought a new set of aluminum Mopar Performance, black wrinkle valve covers from my local dodge dealer. These are for a small block. the covers seam to be to long to sit properly on top of the 340 heads. I used the thick cork gaskets and just a little sealer. Can not stop from leaking on back corners. Wondering anyone else has experienced this problem.

    Never a problem. Check cover and head pan rail for straightness. Check the covers do not sit on the intake when tightened down. It shouldn’t take to much permatex to seal them up.

    yeah, i've had that problem... permatex and keeping them tightened down has solved it for me
