    Gaskets and head bolts are a must to swap heads.

    I would suggest a top end gasket set because you'll need more than just head gaskets and bolts..

    Op check out this section. This swap should be covered in detail somewhere here..

    If not, I'm sure someone with more experiance than myself will be along to help..

    It would also be a really good time to change out your lifters.

    You should do pushrods also Top end gasket kit, Lifters, Lifter trays, pushrods, valvesprings and heads. Headers will fit so you will be good there

    Shit adds up fast

    they are the biggest Men I have ever seen. I
    wouldn't want to fight them!

    I agree with him. That is what i did with my first ls, make sure you shop for your parts and try to use gm mls head gaskets, they are well worth the money if you ever have to pull the head again.
