Need help pulling cylinder head
I need some help with pulling cylinder head
I pulled off all the bolts I thought it would take and when I go to pull it up it doesn't come off.
Give this pic a look. Do I have to take the bolts off the top of the valves?
Any other ideas why the head doesn't come off?
I haven't done this before so I could be completely doing it wrong.

Yes you will need to take the rocker arms off and pull the push rods out. This is the bolts holding the shaft that they are all on. I would recommend doing something to keep them in order like tape to label them, if you plan on reusing them. Looks like you have the exaught disconnected. If memory servs me right there are a couple of head bolts tucked under the rocker shaft. Once you are certain there are no more head bolts you should be able to pull the head off, it might be tough to get off but a pry bar under the intake runner should give you leverage.
thanks rtintwo.
A couple more questions.
1. If I pull of the bolts on the shaft do I have to make sure the valve seats (I think that is what they are called) don't fall down? I know I changed some valve seals on a V8 before and you have to blow air into the cylinder so they don't fall. Or do they fall and when the head comes off you pull them out then.
2. I have the exhaust manifold off. there shouldn't be any other connection to the exhaust, right?
3. I will do as you say about labeling the the shaft bolts but are they all really different per cylinder (I did label the plug wires but I guess I wouldn't have thought those bolts would each be unique). or is it just where they are at.

3. You dont need to take the bolts all of the way out just loosen then and turn the rocker out of the way like mustangftw said. What you need to label when you remove is the pushrods. They are on the drivers side opposite the spring. once the rocker is loose they will slide right out
mustangftp: he has different rocker setup than you. you loosen the rocker nuts, he has to loosen the whole shaft.
so basically (for the OP). get rid of all the bolts on the shaft. the valve springs will push it up. So you can feel it working with a spring when you unbolt them, you know what i mean when you're at it.
as all the posts before. if you can just loosen the shaft bolts and put the pushrods away what is stopping the OP of just pulling the head up? Nothing
what I'd do is (i have no idea about those 6 cyl engines):
- get rid of all the bolts on the shaft (the very top 6)
- pull off the shaft
- pull out all pushrods (label them as #1, #2 etc)
- then make sure you have all headbolts removed
- check if anything is holding intake or exhaust manifold at car
if all that's remove the head has to come out. If not then it might just need a tap with the rubber mallet from the side. but I'm sure you must have forgotten something as otherwise the spring pressure would have pushed the head up already
if you already loosened all headbolts in all comes out then i think you have to remov ethe shaftbolts latre as you can't possibly install it that way. first head on then the shaft. not together

Im sorry i was a bit vague in my previous post. I ment for you to label the pushrods for what spot they came from not the rocker shaft bolts. The push rod ends have a bit of wear on them that matches with the rocker and lifter that they are mated with. This is normal wear and part of break in for these components. It is best to try and keep the wear matched when ever possible. I hope i am clearer with what i mean this time.
Below is a pic of where I am at. I pulled off the rocker arms and shaft but still can't get the thing off.
I don't see any more bolts but when I pulled on the thing I get nothing.
Worse I chipped a small bit off of the head where the exhaust manifold attaches.

There are 14 head bolts. Are all of them out or is one of them hiding under some gunk on you?
ETA: dont be too worried about a chip around the exaust port, ford made them generous to begin with and when you get the head to the machinest he will be able to work some magic for you on it.

If you are certain you have all the head bolts out then its time for a big *** hammer. A dead blow hammer is the best cause you can haul off and whack the SOB. You will be creating vibrations in the head that will loosen the 40 year old gasket that being stuborn.
