Hey guys,
I'm trying to find the bolts or studs that hold the exhaust manifolds to
the heads on a 351m. I work at napa and didn't have any luck looking them but if you guys know what size they are I'll just run some grade 8 bolts in them, at least for the time being.
definitely agree with that! pain in the neck once they go hard. Stainless can bite you too. Won't rust easy, but if they break can be a mongrel to drill. Always handy to get some anti-seize(copper or nickel) and use on these and other bolts that may be a pain later to remove especially ones that are heated.
