Get it running in a perfect stock condition - valve adjustment, distributor advance curve, plug gap and indexing, send the injectors out to RC engineering for cleaning and balancing, test the entire engine wiring harness, test all the sensors to be sure they are in spec, fix all the oil, fuel, and vacuum leaks, fix any intake and exhaust manifold leaks, check valve spring pressures, etc. If you make sure its in perfect stock condition you will more power then most of the folks who mod a poorly running stock engine.
