I have tried every size socket ...I'm pulling the head today but the boots won't come off

It's just a 12 point socket.

It is much easier if you untie them first.

It's bolts...(using my Droid)

ARP head studs are, studs. Therefore you are trying to remove nuts. Sorry for being a pedantic jerk. /ubbthreads/images/graemlins/grin.gif

Omg.ok nuts ...now I need a 12point but what size...I'm sitting at homedepo waiting for a reply

I wanna say it is 12-point 14mm, not sure if it needs to be deep or not.

12 pt 14mm and I use the deep socket for the extra reach/clearance for the stud. Never tried it with a regular sized socket... /ubbthreads/images/graemlins/dunno.gif

i use a 9/16ths deep 12 point

You've got a galant vr4 with arp studs and you don't own a full compliment of metric tools? You can take apart just about the entire car with 10, 12, 14 and 17mm sockets and wrenches. A couple of each is a really good idea in both standard and deep sockets.

^ He speaks the truth.
Although off hand I can also remember need a 27mm socket for the axle nuts.

which is the same size as a 14mm.

Close, but when messing with stuff that gets torqued tight, use the right tool, and not that ching chong crap from home depot.

Yeah, a 9/16 is close, but on something I need to torque to ~90ft/lbs I'd rather have the *exact* size socket, and a decent quality piece at that.

it ended up being a 12 point 14 mm..thanks everyone
