Hi guys,hey I've got a set of 2.9 heads on my workbench with the rectangular not the oval rocker pads like the pics in the tech library but there was an 86TM along with a 6090CAB casting number next to the middle spark plug hole.It also has an 89 cast near the middle rocker pads and C8S1A cast near one of the end intake ports and the 8mm instead of 10mm ground bolt on the end of the head like someone said .My bronco was born in February 1989 but I didn't think the new heads came out until late 1989 with an 89TM casting number,do I have a transition era heads or something, just curious.
