So i was looking around for parts, for when i swap the 4.8 for an LS1 and i came across these airflow research heads and i was wondering if any of you had used them? They will fit our trucks stock as a direct bolt on, so i was thinking of getting some for now bolting them up to the 4.8 then when i can swap motors i can swap the heads, too.![]()
