Yep, twisting them, vertically, had them going before they got stuck. A search here yielded a suggestion of using WD-40. I gave each a goodly shot, and after ten minutes or so of soaking, came back and twisted them some more. They worked their way out nicely! After wiping off the injectors I now have the whole rail assembly pulled out of the way, but covered in a clean plastic newspaper delivery bag for safe keeping. Surprising that I didn't need to discharge the fuel pressure!
Then the timing belt came off -- interesting eccentric/cam design to the tensioner.
Then after removing the four hold-down bolts, the throttle body wouldn't budge. A wood chisel and a whack separated its stuck gasket.
Then, looked straight down the huge intake manifold ... and the "oh sh**" moment, large, shiny silverish chunks of metal in the bottom.
Pulled the very long but small headed intake to block bolts, and have the intake hanging. Used a piece of wire to help support the exhaust, via the power steering pump bracket.
Head almost off, probably after dinner. Looking down the #1 and #4 spark plug holes showed the very carboned but oily tops of their pistons, and no shiny stuff.
