    Looking at my exhaust manifold bolt holes and the bolts, there is about 1/8th inch gap, is there suppose to be that much slop?

    It's been a while since I last took a set off, but if I remember correctly they ft in perfect.. No slop but enough room to slide on in with no friction, I think you have a problem.

    But remember.. Been a while ad I could be wrong.. But maybe you got the wrong bolts, do they thread into the head?

    yep, the bolts do thread into the head. I see what Comet Fever is talking about though, the washer allows for the bolt to center with the exhaust manifold.

    My 250 had some " wiggle room " on the outside set of holes. I don't think it was ⅛", but it could have been. The V8's are pretty tight fit, but I think the 6's have play so the long manifold can expand when it gets hot. :)

    That's where the top ear broke off of my head! Luckily, there was more of the hole thread left, than broke off. I put the broken piece back on with " JB Weld ", and put a nut behind the ear when I replaced the gasket. It's still going strong!
    And in response to " Frank ", the manifold in the photo looks like all the holes are enlarged. Just the front and rear ports on mine were enlarged. I wonder how many different manifolds Ford made for one engine? :hmmm:

    7 of the holes have the larger holes, I looked at the exhaust manifolds from a Lincoln Continental...there the same way. Wonder if it's for expansion/contraction. :huh:

    My 1974 comet has one crack in it, it's only got 16,153 miles on it originally. Cracked towards the front. :hmmm: The guy I bought the car from tried to fix the gasket , but could not get the bolts off. Rust from sitting did this an road salt.

    @Comet Fever, I see in your photos that you have your temp sender what looks like in the thermostat housing. Did you have to drill and tap the hole? I put mine in the back of the head where the sender for the light was. My thermostat housing has a place that looks like you could drill and tap it, but it isn't very big. :)
