    I want to replace my valve cover gaskets on my '84 K5 with a 305 since I have a leak that is making a little smoke, I unbolted everything but can't get the cover to break loose. I know you're not supposed to pry it off since it will bend the cover, and I've tried hitting it with a rubber mallet to break it loose but nothing is working. Any suggestions?

    Thanks!

    Just down or from all sides you're able to get to?

    It doesn't budge from anywhere, anyside, etc... It feels like it's glued on or something, haha. I've never done this before so maybe it's normal and I'm not used to it, but damn it feels like I didn't take any bolts off.

    there is probably sealer on the existing valve cover gaskets.... You can pry the cover off with a flathead screwdriver, just do it a little all the way around making sure you don't use any excessive force that will bend the cover or cause any damage to the head sealing surface.

    It sounds like someone RTV'd those suckers on. Use a small screwdriver, and work gently at it. They will come loose, eventually.

    Stuck valve cover on a 305 would be enough for a engine swap..just kidd'n..

    On engines that are in running condition I warm them up a little then loosen the screws and tap on the cover with a rubber hammer until the gasket comes loose from the head. I then snug up the bolts and let the oil drain back into the pan and any hot parts can cool down.

    If its a non-runner then pry...beat...hack...repeat!

    while i think the screwdriver method is best, you could potentially put a small piece of 2x4 against the valve cover and really give it a good whack with your mallet. the 2x4 would spread out the force evenly so as not to dent it anywhere.
