FastDriver said:what are your future plans? If you plan on expanding to a stroker motor or going with forced induction, I recommend going with the 185s. If you're set on staying with the 306 for a long time, the 165s are the right choice.

You've made a fine choice. You can rest assured that your going to be VERY pleased with your choice..though really any of the top five heads in that category would "feel" the same on the street. The difference in flow numbers and HP numbers is not something your going to notice stop light to stop light. Where you can really separate yourself from others would be in the cam and other supporting hardware selections. Pick parts that work together and that little girl will fly.fiveoho said:not the first time ive heard that either. i WANT to do a charger later, but i doubt that funds will allow me to do that. have a strong feeling that it will be a NA 306 the rest of its life.
so i done ok with the 165 choice?
..had i gotten the 185s, would it have helped me or hurt me or left me the same on a NA setup?

If i were you i'd probably think about getting a track heat or something that flows similar.
Redrooster said:You know you can get the TW with cnc porting from the factory now. They are really nice. They have a 185cc intake port and flow around 300 cfm which spanks the AFR 185 pretty good. If you are planning on moving up in power later this is the way to go IMO. They still make the great low-end power of a regular TW but with awesome hp potential. You would have to port the AFR's to make those kind of flow#s and then you would lose more low-end power.
