I noticed that no one really makes a throttle body spacer for the earlier 4.0 cherokees like mine (89'), why not? I can't really see why not but thought I would ask before I construct one. Also does anyone know if there are bigger valves or performace heads for the 4.0, would like to port my intake and hone out the throttle body but would like to work on the heads first. Thanks!
