Ok, so it sounds like the 351 heads would be a good bet (plugs are available, good flow etc). Here's the combo they would be with. Stock HO upper, Holley Systemax 1 lower intake, stock HO cam, 19# injectors, D9S ECM. There will be a 3/8" spacer between the upper and lower. It's a must have to clear the fuel rail on the drivers side. I doubt it will make any difference performance wise.
Sound like a winner?
