What should I consider when switching to a high compression head?
#7
If you have standard valve gear there shouldn't be a problem, but otherwise you might want to check the valves don't foul the head.

As with any tuning mod, first make sure the bottom end is sound. Increased compression should give you better performance but will place more strain on your crank and bearings accordingly. I would also check the compression ratio as people sometimes get carried away and skim the faces more than I would consider wise.
