Certainly thoroughly check the block and head. I had a leak in the same spot. Cracked head in multiple places and slightly warped deck (P.O. beat the piss out of the truck in the mud). I o-ringed the head (easier to replace/fix if something goes wrong).

I used a couple light coats of permatex copper seal-a-gasket on both sides of my Cummins hg. Holding up so far!!!

Don’t be so crazy about a “smooth” surface. The gasket needs something to bite on to. Levelness and cleanliness are the two most important factors. Otherwise, enjoy!!! Straight forward job.
