Prior to hoisting the cast-iron heads out of the engine bay via cherry picker, Flynn zip-tied four of the bottom five bolts in place on the driver-side head, along with the rearmost bottom bolt on the passenger-side head. This is done because these head bolts can’t be removed due to clearance issues, and you don’t want them to drop down into their respective bore and potentially reengage any threads while you’re trying to lift the head(s). Flynn finds that zip ties work much better than the rubber band trick, which is promoted in the Ford service manual. Also notice the exhaust manifolds are still attached. According to Flynn, there is no need to remove them unless the heads don’t check out OK at the machine shop, and there is no need to disrupt a good seal (only to battle rusted, corroding manifold bolts) unless you have to.
