So i put loctite on the studs and put them in the block, put the head on and lubed up the threads. When i went to put the nuts on they don't thread? Does anyone know what size the nut is supposed to be? The ones i have are M10 x 1.25. B18b1 block / head the ARP set i have is 802-4302. Now also what i'm worried about is that it's been sitting for about 5 hours and the loctite is dried and the insturctions say to do the final torque on the head before it dries, Is this going to be a problem?
