The only references to the SCV-8 Blue Roses I found were on many custom valk models posted on these forums - before that I had never heard of them, hence the reason I asked.
I couldn't find any reference to them either of the Variable Fighter Master File: VF-1 Valkyrie book #1 or #2 (I don't have the Squadrons books yet). Nor was it mentioned in This Is Animation: Macross Plus Variable Fighter's Aeroreport where some other squadrons are.
As for the SVC designation, there are references to SVC-133 "Starhunters" (pg125) and SVC-131 (pg91) in the Variable Fighter Master File: VF-1 #2 book.
I actually was organizing a list of the printed squadrons (bored waiting for the VFMF Squadrons book from HLJ) when I came across multiple posts here talking about SVC-8.
