i wouldnt bother doing any kind of work on a 3.8 if thats what your thinking.

but if your doing E7 302 heads, then it is definately worth it. I did it and noticed quite a bit of gain for the work i had in it. I did most of the work myself with the help of 302man. If you had a shop port your stock heads then its not worth the money, but if you do it yourself then its worth it.
