4.6 L Jegs PI heads and Intake
Anyone used the PI heads and PI intake from JEGS? If I pull mine, 1997 4.6 , which are in need of repair, I am planning on new or just get rebuilt heads to swap out to reduce down time. Any one know what else will need to be done going to the PI heads? Brackets not aligning, new PCM or computer programming etc... ? How much performance increase will you get from these?
