Question on swaping heads
lol had to do it Thanks for the info, I did not want to buy a head cam package just to find out I needed new headers as well.
I think you'd definitely see an increase in power with just heads - although, to really shine, a new cam would be a great as well.
The AFRs are a much better design than the stock heads, therefore gains can be had. Better runner design, better chamber design, etc...
Good luck.
