Cam Id help needed

[DesmoS4]

Morning Gents & Ladies 

So I’ve got these NOS cams knocking around and as I’m about to give the slabby her winter lay down service I wondered if they would be worth swapping in

Current set up is 750F bottom end mated to a 750L head running 750F cams, carbs are RS36 flatties with K&N pods, exhaust headers are from a 750RRK into a 60mm link pipe to a shortened Akrapovic end can off a ZX10R 

Part numbers are

Exhaust

Inlet

Both cams are stamped 27A the exhaust is also marked with a C and R1 M. The inlet is marked with 27A F and R1 M. 

If I remember rightly 27A designates Slabby part identification but the searches I’ve done have been inconclusive. 

So what are they and will they work together and will they give me a worthwhile boost to what is already a pretty potent engine 

Cheers Desmo

Only way to ident them properly is measure the lobes and compare against specs.

All oil cooled cams have 27A on them, and bits stamped on the ends dont relate to engine/model either.

Exhaust cam is 1989 750rk and intake is 95-96 750f that's going off the part numbers you have in photos.
