There are a ton of variables to consider before purchasing either the 38cc or 44cc Trickflow heads. Based on your question, you obviously will have have forced induction via a supercharger.

The 38cc heads will raise your compression by roughly a half of a point, whereas the 44cc heads will keep you pretty much at the stock 8.5:1 compression ratio. Other than that, these heads produce the same flow numbers.

Regardless of how much boost you plan on running, both heads will flow more air and produce more power than stock 'PI' heads.
