no.
the 24 valve is the best core out there because of the wide LSA 107.5 vs the 99 LSA of the 12 valve . The old non IC 12 valve cams had a 108 LSA but are hard to find. The CR has a lot better timming , but the tight 98 LSA makes it a passive EGR cam. The LSA need to be at least 110 to 114 to acheave what a diesel wants .
