This is very interesting... I have a shop (A Very Good Shop) rebuilding my Twin Cam as we speak. Got the head back from the machine shop yesterday. I bought ARP bolts for the whole engine, I may have to relay this message to them, since I'm not sure what ft lbs they will use.
I didn't open the ARP packaging. They know what they are doing but raise questions for myself. I'll talk to them and see what they recommend.
Thanks,
