How can you tell if a car is a Big Valve or not?

All 500's were (apart from a few 'modified' like Quinny's), some 430's and various 450's..
No 400's, & only a single one upgraded with BV heads that I can recall (bit OTT for 400).
To check the valves you need to pop the retainers off and inspect the valves with a magnifying glass just under the grooves. All the BV valves are faintly stamped REC 460 & 461 (in & ex).
