Couple ideas:
Give the Spree parts compatibility thread a look
Powertrain/exhaust swap should give a small speed improvement, taller gears, domed piston, slight port timing diff. Some use the '84/85 head on the 86/87 engine for higher compression. IRC there is a minor electrical diff at the pickup coil (just leave the extra wire unconnected) and rear brake cable.
