I'm presume they are the BOP type, since that is what my engine is. The
specific oil pump that I have is for the GM metric V6s. Of the two styles
of relief valves I mentioned one of them is for the metric pumps and the
other is the factory BOP style and probably early Rover and Buick 300. I
can't say anything about later rover pumps because I have never had the
opportunity to look at one. Hope this helps
