Water Pump Vs Timing Cover Conflict

same gasket on a 63 casting and a 68 casting....dead nuts on. My iron pump is on my 3rd 86 cover, no issues. I bevel the ends of those bolts to assist picking up the threads. Those bolts take some abuse as water jacket. Maybe that water pump is a replacement casting as mine has the threaded boss where your blank is.
(disregard the gaskets that are on backwards...Doh! :p)
