Magnum 360 roller cam block, MA-X Indy heads & more

sounds killer; assume race gas w/ flat tops and 62CC heads ??

Bob- a guy can use 93 octane at sea level. These magnum heads are super efficient. Static C/R is 10.6 to 1
E-85 setup, or fuel injection or race fuel (depending on application) would be great too.
