Cheap flow???
 

If I bought a new set of untouched twisted wedges, what would you recommend doing to make them flow a little better without spending much money? Multi-angle valve job??? Port matched to intake?? or should I just leave them alone until I'm ready to spend some money? While I'm on the subject of flow, is a 3/8" intake spacer worth installing on the street heat?

I would say save up your money and wait to have them done the way you wan't once... Some porters won't touch a head if it has been messed with by someone other than themselves before...

Intake spacers are always a good idea, they help isolate the upper intake from the lower, helping to reduce heat transfer leading to a cooler more dense intake charge... plus they will add a little volume to your intake, being good for low-mid rpm power...

hope this helps,

Intake spacers are a waste of money, and they create more low end power, by making the runners longer, not the other way around.
