Zero compression....video and pics

Thanks, Newmechanic! This won't be for probably at least a month but I will remember your thread. I don't have that repair manual and I have a F155 and not a 2f but....hmmm, would they be the same specs? It might be here on Mud, too. It always amazes me that something as solid and heavy seeming as a head can warp and bend. It certainly would be nice to not have to mill it as I imagine it would add a lot more down time to the truck.

Ok. Then for archival purposes, here is the data in case you need it, or think it might be useful.

there is a flatness test you can do with a straight edge like a metal ruler and some feeler gauges to check the amount of bend in the head,

A 'metal ruler' isn't going to cut it. If you're having a shop do any head work, have them check the head for warpage using their equipment.

Thanks guys. My approach for now is to order the necessary gaskets and such and get back to the truck and have at it. I'll talk with my buddy about the head shop and how much money and turn around time is involved. I don't want to sink more money than necessary into this truck/not looking for perfection. How likely is the head to be warped? Is it quite common?

Unless it was overheated, I would argue it's not likely to be (very) warped. I'd be more worried about cracks in the head, which can also be determined by the machine shop, and should be done before any machine work is performed.

yeah but I don't WANT any cracks in my head! If I have them look, they might find one.
