What type of riding do you do? You want to buy pipes that fit the type of riding you do. I would go with chrome, but thats depends on what look you want. The reeds and timing plate will be fine with t-6's.
If you plan on doing more work to your motor in the future like porting, 4mill, performance upgrades I would look into a different pipe, t-5's, cpi's, ect....... The t-6's are more for a stock motor (unported stock stroke).
I would recomend a cool head, 21cc dome's should be fine for 93 octain.
Good luck with your build.
