Ok, my car currently has the heads below in my sig. I got them with the car i bought from the guy. As it says below, completely redone, ported, and milled E7 heads. My question is how good do you think these these are compared to aftermarket heads such as AFR or Edelbrock? (I've heard good porting/milling jobs can add up to an extra 20-25 hp). Would it be worth spending around $1000 to upgrade. I probably do not have enough funds to port/mill the aftermarket heads (btw how much does it cost).
So the final question is: Are my ported/milled heads just as good as unported aftermarket heads? Will they work fine with a possible supercharger in the future? Any help here is greatly appreciated.
