The number on the diagram you are talking about http://suzukisavage.com/images/uploaded/HeadPattern01web.jpg is the length of the bolt.  You can buy them at those longer lengths from most internet bolt suppliers a lot cheaper than from Suzuki.  

We generally replace them with the much stronger stainless allen headed bolt kits (see Ebay for availability).   The stock Japanese head cap bolts are soft crap, not to be reused if you can avoid it as the head cap comes on and off several times over the life of the bike as you deal with head plug and cam chain issues.

Next - your torque requirement for those locations is 100-120 inch pounds (8-10 foot pounds).    You are exceeding this by a good margin for you to twist those bolts off.   A small inch pound torque wrench is needed to properly install the bolts in the proper criss-cross pattern.

Who told you to put loctite on those head cap bolts?  You just bought a world of trouble as when they break off down inside the head on next removal they will be a bloody mess to get out.  

The long skinny bolts simply are not strong enough to support the force required to break the Locktite free on the next removal, especially if you overtorqued them to 85% of the breaking point on the install and put Locktite on them on top of that.

Neversieze I could understand (eases the next removal and keeps corrosion lock up at bay) but Loctite on the head cap bolts, never.    They are not vibration loosening up type items in our past list experience, but they do have a long history of breaking off down deep in the holes and being a pain in the butt to drill out of the head.  

Machine shops get them some work from those long skinny soft bolts, they do
