what do I do now

I've been researching the same with a pair of 360 heads I have. I came up with "rebuilder" valves slightly larger head 1.94? 1.62? to move the seat outbound available with oversized stem also. Mine need cleaned, surfaced/milled, valves, guides seals etc. Not sure if it's really worthwhile so the magnum EQ swap is starting to look more attractive at this point.
