THe various protein databases do clustering of genes.
You might want to use the number of species or gene copies in a gene cluster
as a measure of convervation. E.g. Uniprot's UniRef data set.
http://www.uniprot.org/uniref/?query=histone&sort=score
(max 5,345 genes at 50% identity)
versus
http://www.uniprot.org/uniref/?query=obp&sort=score
(max 23 genes at 50% id)
