hey guys looking for opions on this i have a new cam 212 220 .579 .580 on a 114+4 to go in i am debating on spending the money on ported heads by tea or putting vavle springs and retainers on mine and buying a radix.what do you guys think? thanks

 

Forget the heads and buy a supercharger....

Heads are a poor return for your money.

 

You'll get bigger results from the Radix. That cam should be a good boost cam too. Beware, you may need contom tuning to get the best results out of it.
