hey guys glad to be back on i need to remove my exhaust manifolds. i can tell that these have never been off before. ive been putting on penetrating oil for about a week. my socket wont fit over the heads they are rusty and look odd shaped from layers of rust a friend told me that factory bolts had a lock so to speak to keep from vibrating out so the bolts will look to be deformed and that a flat head to push those down will let the socket fit. is this true? also how many bolts per manifold? what kind of chemical can i use to bring the rusty manifolds back down to metal?

any help would be great

thanks
