I am changing my 2000 cylinder head (cracked at 190,000) and am now removing the intake / exhaust manifolds.

It seems that all the bolts are 9/16" except for the two studs at either end of the cylinder head which have torx heads.



What sort of tool would I need to remove this? And what size? This is not certainly not something I have sitting around in my toolbox.

Isn't that going to be removed with the same socket that removed the rest? then use the torx to remove the entire stud from the block? That's what i would think looking at it...

Just remove the 9/16 nut from that stud. There isn't a reason to remove the stud though. To remove the stud use something like these.

Thanks. Saw that kit. Anyone know the particular size inverse torx bit so I don't have to buy the full set? I do need to pull the stud to put it back into my new cylinder head (Clearwater) so I need to get it out one way or another (or buy a new stud),

You are most likely going to break the hex portion of the stud off when trying to remove it. I would just get 2 new studs and dont worry about taking them out.

I'm leaning in this direction. Do you think I could find studs at NAPA or do I have to order online (I'm on a time crunch)?

For future reference in any case seems the OEM is a size "E-8" FYI.

I think I used a Dorman kit when I did mine. It's pretty common and should be in stock at some auto store:

9/16" is the size but those studs are rusted in there bad and not moving, even with vice grips. I ended up ordering the Dorman 03408B Exhaust Manifold Hardware Kit (solely for the studs) and will drop these in my new clearwater head.

double nut the stud and pull it without special tools , also the socket that fits the stud is called a etorx but I can not remember the size
