Tonight I have decided to remove the head on my good ol' fj. in a book, it said that I had to remove the valve lifters, is it necessary to do so? and if so, could a guru or anyone of the matter point me in the right direction and give me some tips?
greatly appreciated in advance.
 
Assuming you're referring to an F engine similar to my F155:

First question: after a night's sleep, do you still want to remove the head?;)

2. Why?

3. Do you have a replacement head gasket and valve cover gasket?

4. Since you "should" remove the pushrods before you lift the head off, you could loosen the valve lash adjusters to release the tension on the pushrods, then remove the rocker arm assemblies by removing the bolts which fasten them to the head.

Note that there is an oil supply tube feeding the rocker arm assemblies which needs to be disconnected. Be careful NOT to snag it when you lift the head off.

IMPORTANT: LABEL EACH PUSHROD WITH ITS POSITION (1 - 12), front to back, so they return to the lifter they've mated with.

5. Refer back to steps 1 and 2. :worms:

I have a suspicion and symptoms of a blown head gasket, that is my whole reason or I would not be striping it all down in the first place. I already got the gaskets for it and have been working to get them all in. i have numbered every pushrod and removed them sticking them into cardboard, a good trick, so if there is no need to remove the lifters and the head can come off, it will today, and thank you for the heads up about the copper oil supply, nearly forgot about it.
cheers

Sounds good. Don't forget, that head is very heavy.

Good luck!

this. I have a supply of fender washers, and I tuck one under a 10mm nut of the front and rear rocker studs to help lift the head off. A good towel over the radiator, and a piece of wood from the radiator to the driver’s side apron. Stand on the passenger side framerail (right foot) and battery tray(left foot)

Grunts and other sound effects help too. ;)

And don’t expect a YouTube video! :p

for the reinstallation of the head., do you need the side cover off to realign the pushrods on the lifters or are they sliding exactly where they should on the lifter without the need to be hand guided ? i may need to do the exact same thing. thanks

Nope. At least not to my limited experience. Just drop 'em down the holes.

The bottom of the push rod lifter is flat, the top of the lifter push rod is flat, so the top of the lifter is concave, and the bottom of the push rod is round. Thanks to @Pighead for catching my mixup. Can't do this stuff while talking to the :princess:

Is not the top of the lifter dished?, the bottom of the pushrod the balled end?
