Long tube headers
i dont have info for you on you Q. BUT ill give you a hint. most of the time headers make getting starters out very hard. so get a new starter to put in before you put the headers on. hint 2 use anti-seize compound an ALL threads on header AND on the bottom of truck. on the header put bolts on at 70-80 % of full torque, after 5-7 full heat cycles take to full torque. if it leaks be for that take to full torque.
