Repeated head bolt removal or a stripped block thread usually means either a helicoil repair or a trip to the machine shop, both of which add time and cost to a rebuild. This stud steps up to a larger 1/2 in. block-side thread while keeping the stock 7/16 in. nut size at the head, salvaging a damaged block without a repair insert.
