<font size="2" face="Verdana, Arial">no, you would get the same increase. It's still the basically the same head. You can't port the svt head any more than you can port the zx3 head. Likewise, if you raised the compression on the svt head you could do the same on the zx3 head. It just costs you more to start out with svt parts.Originally posted by iamgod:
yes but doing the same to an SVT head would yield a proportional increase in performance...
<font size="2" face="Verdana, Arial">if you buy a head from FS, you just mail in your old one after you get the new one. Better yet, FocusCentral just gives you a new head without any core exchange.and since you would need to supply a head to be altered sending the SVT head while keeping yours on the car would help keep down time minimal.

...ditto for the duratech head since it flows better than the SVT
