My engine build was humming along great until I bolted the heads on. The head studs are sticking so far above the nut, a few of the rockers are hitting the bolts. It looks to me that these studs are longer than stock. My case has the 8mm case savers and I checked that the studs are bottoming out. They are about 25mm into the case. I have all studs in the their right place so I can't understand why they protruding so much. I have attached a few pictures. Any thoughts or comments would be welcomed.
