Hi Willa,
It's difficult to tell from the angle of the photograph, but are those cams both the same length ? If so they are most likely from the Elan/Ford TC engine rather than the Europa - the Europa inlet cam has an extra bit on the end to drive the alternator pulley. The exhaust side cam is the same on both the Elan & Europa. They look to have a single groove which makes them S/E cams like the ones in my TC (non-big valve) Europa.
As a guide the Europa inlet cams aren't as common as the Elan ones, I paid £125 for a s/h inlet cam last year and considered I'd done very well. Even Elan cams are going to be somewhere around £100 or more depending on condition & profile.
New ones are available for both Elan & Europa but much more expensive, £230+vat each from QED in the UK for example.
