Your picks will work excellent. I'd personally spend a extra 200$$ and but the Track upper though, the Street won't breathe as well with the 331, but will work ok. I'd still take the TW's over the AFR's only because they match up better, however the 185's are a little better than the TW's.

TW's flow about 255 @ .500
165's about 250 @ .500
185's abot 265 @ .550

The TW's are a lot cheaper too....about $1000
