Thats exactly what im doing on this car. FYI the “VTEC Killer” phrase you speak of is made for the kseries by Go power, Toda, Blueprint racing…etc The k24a1 head flows just as well as the k20a2 head. When you look at the specs of the a2 cam as well they are more aggressive than the stage3 BC cams for the k24a1. Yet i am maintaining oem reliability because i am running parts that have gone through countless R and D and there meant to work together. I am running exhaust rockers on the intake and exhaust side from a nonvtec car so that i only run on the vtec lobe.
This setup is way more effective in a kseries car than a B. Onefstek dynoed at 281whp 211 wtq with a setup similar to mine. Just a little higher compression, and a ported head and intake manifold. I believe he had a slightly more aggressive cam as well. It was a custom ground a2 though.
