with standard carb cams compression exhaust mods, they can go quite well. but of course will never be a 4AG. my 4K does nicely, around 100hp @8000rpm and very streetable.
4KE and 5K heads have same chamber volume, so stick with 5K head, shaved, clean up the combustion chamber and unshroud valves. open up the exhaust ports, and take intakes to maybe 30+mm diameter (don't quote me on port wall thicknes tho  )
make tuned extractors, get a nice cam, maybe go to solid lifters....
just normal stuff.
