is it hard to torque the head bolts??

I've done both, and I much prefer working with the ARP fasteners. I don't think there's anything wrong with the GM stuff, but the ARPs are easier to torqe, much less suseptible(sp?) to being rounded off (believe me, I put mine through hell), and give me the warm and fuzzies. The GM bolts were tougher to break loose, not reusable, and more annoying to torque down because of the angle thing.
If had it to do over, I would so buy the ARP studs instead of the bolts. I thought that the studs were overkill and not worth the extra money. Then, after I bought the bolts, it occurred to me that with the studs you don't have to clean out the damn bolt holes. That is so worth the extra money!
Studs are just way more consistent. After the studs are set in the block, there is virtually no rotation of the stud threads in the block. Almost all of the rotational friction and thread stress is on the top thread, washer, and nut. This preserves the integrity of the block thread bosses.
For my engine builds, there is no better way...period.

If you're using the ARP moly lubricant (which you should be), I think they call for 75ft-lbs of torque. If you use straight 30 weight oil, they call for 85ft-lbs. You should torque the bolts in the usual GM pattern and do 3 passes. I torque them to 20, 50, and then 75ft-lbs. Keep in mind that this only applies to the larger bolts. The top row of small bolts are torqued to a much lower spec. I can't remember exactly, but I believe it was 19ft-lbs. There should be instructions with the bolts, so check that to be sure.
You seem to be pretty anxious about all this, and there's really nothing to worry about. Don't let the extremists get you too worked up about it. Torquing down the head bolts really isn't a big deal. It's a bit exhausting when leaning over the fender of the car, but there's nothing really hard about it. The worst part of the whole thing is trying not to lose the damn washers when you're taking the bolts back out. That's definitely a good day to own a pen magnet.

You shouldn't have to worry about the ARP bolts much, though. I have split not one, not two, but three sockets on the same damn bolt. Every time the cause for the split socket was because the header was resting on the deep socket I was using (resting on it with quite a bit of force, I might add) and side loading the socket while I was torquing it. No matter how hard I tried, I could not keep that damn header off the socket. Every time the bolt proved to be more stout than my Craftsman socket and split the bastard wide open. There was some scarring on the head of the bolt, but that bitch was stout. I've never seen anything like it.

We'll see how easy it is or isn't to install a head with the studs in place.
