I am thinking of adding an aux Oilcooler. Also thinking of switching to a remote mount oil filter, hopefully in an easier place to get to it. Is there any danger in mounting the filter too high? Would it possibly air-lock, and not allow the flow of oil?

Shouldn't ... it's pressurized.

Maybe this thread will help.

i welded a little bracket on the engine mounting bar. it makes filter changes a snap. it in the lower left hand corner of the picture.

Looks nice! Is that set up for a horzizontal fan?

yes, its a tangerine racing kit. the remote filter is a jaycee 3 port unit.
