Siemens Deka 80's. Done! Tuners love them and they are every bit as good as Ford injectors. All of the specs needed for the Dekas are readily available to enter into the tune. I've used Moates, SCT, Megasquirt and now Holley and never had an issues with the Dekas. They also have an excellent spray pattern.
You'll definitely need an accurate startup tune to avoid issues during break-in. Keep an eye on that AFR gauge and check the temp of each header primary at the head to assure that each cylinder is firing and getting up to temp. Personally, I'd tow it to the tuner and break the engine in on the dyno.
