Looking to get ported heads for my car very soon. I dont have $1300 to just get ported stock heads so i found this guy in my area that can do it for around 400 (very reputable and experienced person, 3 stang guys recommended him).
Now, i have ZERO down time available for my car since its my DD so i must buy heads seperately then put them on later when i have a day or weekend off. Now heres my Q's
1. PI heads are just ported NPI from the factory right?
2. If yes, does that mean i can buy NPI heads and let the guy port those instead of PI heads and get equal flow and power than if i would PI heads? (since its just like a NPI skipping a PI swap and just porting his NPI heads) This yeilds the same results right? (NPI will need more porting than PI heads)
3. If no, then whats the difference between the two heads?
Thanks so much and happy holidays
