Cam identification in a dot head

[antiks]

I pick up another dot head complete with cams but they dont have the infamous "B" stamped in the end, they got a "C" ?
Had a search on here and google but cant find any relevant information.
Can anyone tell me what bike these originaly came out of or have i been given a dot head and shit cams ?
They do have 27A stamped into the shafts.
Is the mark on the ends specific to certain years?

My knowledge of gsxr cams is very limited so any info shall be gratefully recieved.
Thanks

Here a link to cam data for oil boilers that Captain Chaos did up. It may be of some help.

Thanks Jaydee,
Just been and measured my cams lobes,
intake is 33.47mm
Ex is 32.81mm

Looking at Captain Chaos table its close to the 1990 gsxr750 cams from what i can tell ?
Looks like the dot heads cams have been had and replaced with these.

Ask FatBlokeOnBandit, he knows his onions when it comes to Dot heads

Had a look at a few posts regarding dot head cams and someone said if the cams have R1 or R2 stamped in them then there from a dot head.
Both cams have got R2 on them so maybe they do belong with the head.
Ive already got a dot head fitted to my mk1 bandit 1200 but i got the whole slingshot engine with them and the cams have a B stamped on the ends.
Only brought this to store for a future project, they are getting rare to find these days so brought it.
Will keep looking for info with reference to the marks on the end of gsxr cams.
