mine's in the shop as of last saturday afternoon, after i discovered that my mains had a few issues. i'm having them do the usuals, hardened seats, mag etc, and have it balanced. a customer/acqaintance owns the shop, (he just dumped $25K? into a computerized balancing machine), and he impressed me when i mentioned the 'extra' oil line from the block to the head, and he finished the sentence by asking if that head bolt had a hole in it. i'm off to a good start, and have to spend the money before i get the dr bills from my emer appendectomy, also from last saturday
