ok im gonna start buying parts to buidl my engine adn im thinikin about either buyin a used set of heads and porting em but before i purchase i was wandering. would it be safe to port and polish a set of heads that have a 120k on em.. at first i was just gonna buy a set of patriot stage 2 heads then someone told me to jus buy a cheap used set on ebay, and send em somewere to have em ported n polished and itll be much much cheaper.... so would it be ok or would i be better off buyin a new set from somewere

 

Just port your stockers, mileage doesn't really matter though. You're only increasing your air flow.

 

i would port mine i have now... but its a daily driver and i really have no other way of transportation.... so i wanna build a complete engine and take like a week off from work n drop it in when im finished with it..
