Hello, as I've posted before I have an 85 f250 with the 6.9 idi. I'm looking into putting a turbo kit on it, and have locked in a pretty decent deal on a banks sidewinder wastegated kit. I've read multiple places that I need to do the head gaskets and replace the bolts with head studs, which I was figuring I might need to do eventually anyways. I keep searching on here and a couple other forums for write ups on replacing the gaskets, and while I keep seeing links they are all dead or non-working. Does anyone have a good link to a instruction guide on how to do the gaskets?
