RE: should I port and polish my non pi heads or do a pi swap
well i have a pi intake and i thought i would get almost as much hp by p&p my heads....casue a pi swap would be a lot more work and money, so how much would it me to take my heads out and p&p them....
RE: should I port and polish my non pi heads or do a pi swap
its gonna cost more than you could find a used set of heads for. look at it this way, you'd be taking the heads off anyways to have them p/p, why not just slap the pi heads on? i know around xmas time i'll either be doin that or dropping in a 99+ motor
