Is anyone sure these are T/A heads with the offset pushrod holes? They don't look like it to me.
I had a set of U heads and didn't run offset rockers.
I might be wrong, but I don't think the U means it was machined with the offset pushrod hole. That was a separate procedure.
If they don't have the offset pushrod holes, don't think they are worth any more than any other set of J/O heads.
