Will L31 vortec heads from a 99  c1500 fit an'83 305? I knw summit and jegs have a.  Vortec kit that matches the L31's......was wondering. I have an extra set from a 5.7 vortec into jeep build.  Granted i'd have to find a vortec style intake manifold. Would the headers i have fit those heads aswell if they bolt up directly?

Yes, they will bolt to the block. Headers will bolt up but the port shape may be different, you'll have to verify that upon installation.
