The cam retainer plate bolts are 20 mm long , the cam gear bolts are 23 mm long , and the oil pump mounting bolts are 23 mm long , anything over about 25 or 26 mm on the oil pump mount bolts You would run the risk of cracking the block . Not a problem , that's what were all here for . Well , most of us anyway . Good luck

hello , really the best way to check is to screw the bolt you think is close into the hole finger tight until it bottoms and then put the pump , or whatever item you're bolting on the surface where it will be bolted to next to the bolt you threaded in and make sure there is at least 2 or 3 mm to spare . in other words the bolt head should be below the surface of the item to be bolted . If this does'nt make sense to you , reply back and i wil try to explain it more clearly or make a drawing or something .
