It hasn't happened.

72cc chamber stock head to a 62cc chamber large runner ported head. It's not unrealistic.

the reason why i recommend the 317s is that they flow great, will work great, and are dirt cheap. at the limit of your injectors and fuel pump, you will have no issues at all with these.

btw, flow that a1000. some of the older ones do not flow close to what is advertised

save your money because there will be enough unexpected things to spend the money on before the build is all said and done
