There's a few different heads for these, but as it's a hemi engine most likely a mix of both piston and head to determine cr, cam would be fine to use manifold would bolt right up, don't worry about smooth or rough, slightly rough works better, don't want a silky smooth finish.
I use a engine place that do loads of cvh's, could do worse than ring them 01359 251888, ask for brian.
