i have one t3 head from a 91 r/t. it has less than 30k on it, but it does have a small thin crack from the center plug, so it needs welded. it also includes all the valves, springs, seals, etc. intact, assembled and in great shape.
this does not include the cams, rockers, shafts, etc.
$500 shipped, not bad considering less than 30k on the valves, seals, retainers, springs. i will insure it to $700.
