That's surprising. I'm curious if you are using OEM head bolts, or just plain stainless. Most Ace/HD grade stainless is not designed for torquing too much. The nickel plated OEM bolts will have no problem handling this torque.
My builder recommends 20 on the head bolts and 36 on the girdle bolts:

I even used bolts from another engine just in case there was a bad batch in the engine I was running. I still managed to break one from that other engine. Are there bolts that can be purchased other than OEM that will suit the job?
