Would 264/272 cams for an Evo VII work on an Evo VIII?

 

Yes, they are the same.

 

My Japanese reading is pretty poor, but looking at some Japanese websites, it appears that HKS lists the same camshafts as being applicable for all CT9A Evolutions... The Evo 7 and Evo 8 are both CT9A Evos.

So I think the answer to your question is Yes.

 

Yup. They will say EVO VII when you get them.
Same cams.
