Hopefully this is the right place for this. I am basically looking for some knowledge about what to do with my motor, as I don't have a lot of knowledge in this area. I have a 1988 Mustang GT, and I plan on cleaning up the bottom end and leaving it stock other than some new rings. I am looking at getting some GT 40 heads, here is what I would like to know more about. What can be done to the heads, to improve their performance? Can a simple port job be a worthwhile investment without rebuilding the rest of the head ie; stock valves and springs? Also I hear talk of 1.7, and 1.6 ratio rockers. What does this mean? Also I was wondering if there is a Speed Density friendly cam that would work well with a set of GT 40 heads, and also whether I would benefit from an after market intake or whether the explorer intake would work best.
Thanks for helping to build up my knowledge on this subject.
