there was also some chatter on here about using the GA16DE pistons AND RODS for a long-rod E16. this'll get you better dwell and lower peak piston speeds for better ignition and less piston side load.

ah. there's a pic you threw up already... that's the deal. just cut some valve reliefs. you should be able to have a shop mill them in, provided you know the diameter and depth. the dia you can measure, and the depth can be measured by a decent shop with a depth gauge, you'll just need to make a plot of piston height and valve lift (from head surface) vs crank angle and do some addition/subtraction.

blown, PM'd ya.
