IMO if you can not freely rotate the camshaft (s) shafts with the cam caps secured even hand tight on or off the short block.... dump the head.

Other wise the rule of thump for myself and Mike (Thumper Performance) is a maximum .30 from oem (never been surface). Keep in mind this will also effectively raise the CR by aprox.1/2 point. However the head or engine machine shop doing the surfacing must determine what they will surface a head at in which they determine to be their safe limits and you should take their advise.

I would check the the block as well before investing. Check the top of the block for flatness and make sure the the cylinder walls didn't bow out.

It is a nice thought but really does not apply so much to the Chrysler 2.4 cast iron block. The castings are thick and the water jackets plentifully. It would be nearly impossible to change the deck condition from factory specification on these engines. They are pretty bullet prof in that area.

I would have to agree with Lynn(AKA) NitroPT. On the block. If you have any cam rock. Get another head.
