Alrighty, it's finally time for a new OEM headgasket and ARP headstuds for my D16Y8.
While the head's off, I'm going to get it resurfaced and replace my water pump (OEM Honda) and accessory belts (timing belt's already been replaced). I believe my head is warped for sure (been overheating for 8 months or so), but I need to know how to check if my block is warped and what steps I should take to get it back to it's proper surface level.
Now, on to the headgasket / headstud install.
-What brand / type of copper spray do you recommend? I've heard that Hylomar is good to use (whatever that is).
Let's come together and figure out the proper torque specs for my head-lifting SOHC beast.
-ARP says 60 ft./lbs. with their lube, or 70 ft./lbs. with 10w-30 oil. Should I torque the headstuds to 60 ft./lbs., drive for 100 miles, then re-torque them to 65 ft./lbs. for good measure?
-Do I have to take the head off again to re-torque the headstuds?
-In regards to torquing the headstuds, how does the double-nut method work? I've never tried it. Hand tight is what's recommended, right?
-When I torque them down, how many steps are recommended? 3? 5?
-One of my exhaust manifold nuts is broken off. Is it easy to replace when the head is off the block? How do I do it?
-Do I need to take the intake manifold off when removing the head?
-I have a Haynes manual for my car. Will that be sufficient for proper torque specs. and whatnot?
-Do I need to replace both my oil and coolant? I'm figuring yes, but it doesn't hurt to ask.
-Do I need to remove the cam from the head before I remove the head?
I'm sure I have a shitload of other questions, but I'll stop here.
Keep in mind: I've installed my own turbo kit, done a valve adjustment and helped install my clutch, but I have never removed a head from a block. So I know nothing as far as various tips and typical procedures involved.
Help a H-Ter and many others out! I even said please, bitches.

I just picked up whatever napa or kragen had, it worked fine for me.

I used oil on mine, and they were torqued to 65#. This is on a d16a6
-Do I have to take the head off again to re-torque the headstuds?
Definitely not. Just the valve cover
-In regards to torquing the headstuds, how does the double-nut method work? I've never tried it. Hand tight is what's recommended, right?
The directions say hand tight, for mine there was a spot for an allen wrench on top of the studs. I used an allen wrench to tighten them down to the bottom. I just used it to get to the bottom, didn't push too hard. Not sure if this is suggested or not
-When I torque them down, how many steps are recommended? 3? 5?
I think you'd be fine just doing 3 steps or so. I dont even think I did that, I think I just tightened them the first time, and then double checked.
-One of my exhaust manifold nuts is broken off. Is it easy to replace when the head is off the block? How do I do it?
It's easy. Is the stud still sticking out a lil? Just take some vice grips and unscrew it out. Buy another and replace. (if it's a tight fit screwing back in, use the double nut method
-Do I need to take the intake manifold off when removing the head?
I did, just to make things easier. I just disconnected it from the head and left it in the engine bay still connected to everything.
-I have a Haynes manual for my car. Will that be sufficient for proper torque specs. and whatnot?
Not sure, I used to have haynes. But then I bought a helms online and have never looked back. The helms is god for anything you do!!! You might be able to find a copy online
-Do I need to replace both my oil and coolant? I'm figuring yes, but it doesn't hurt to ask.
I just drained all the oil, and then drained the coolant from the bolt in the front of the block. This way I dont have to replace ALL of the coolant, but it's below the head surface so I dont get it all over.
-Do I need to remove the cam from the head before I remove the head?
no you don't have to, but it'd probably be easier to remove it first
I'm sure I have a shitload of other questions, but I'll stop here.

Here are a few comments
1. You don't need to take off the head to retorqe the head studs. For D series motors its actually quite easy, since the cam doesn't block the head stud. Just remove the valve cover.
2. Double nut trick is just fliping one nut upside down and one the right way and tightening them against each other. This will allow you to make sure the stud is all the way in the block.
Check this tread it has alot of info on ARP install

3. For me I didn't have to remove the cam to remove the head. But the motor was out of the car so it made it alot easier.
4. Can't really vouch for Haynes manuals since I don't own one, but HELMS manual get a
Hope this helps some

I pulled my head off today and i'm taking it to the machine shop tomorrow to get resurfaced
. If you use the double nut trick I would torque the studs into the block at about 10-13ft/lbs. Thats what I did last time anyways...too much hassle though. This time I just made sure they were all snug using an allen wrench. I hope this fixes my problems...(prays to god the block isn't warped as well).

a tip for people like me who has changed headgasket with stock bolts, and dont yet have the ARP studs
when u put new oil on the bolts, dip them on fresh new oil, and place them for 2-3 minutes on a clean shop rag
reason for this is so the excesive oil drains off the bolt, and when u drop the bolt thru the head down to be torqued, the walls and the gasket and all that stuff doesnt rub some of the oil off and then it gets between the ehad and gasket and block
happened to me when a buddy helped me out and just dipped them on oil , drop them in, and got oil all between the clean surfaces....and i leaked a lil oil
