Is there any difference between the 7m head from 90 to 91? I'm asking this because i got a head with 90k on it from a 91 na and would like to also know if would be better to use than the head that i have now with 130k on that i will be doing the hg on. Also anyone know what a used isc and cold start injector are worth?
