I've heard STI5 but i'm using 01WRX ported heads and standard cams with mine because for 1, i don't think they are actually that bad and 2, I could'nt get a definate answer whether changing cam profiles etc was a better route to take. So for the ease and cost of it i stuck with the 01heads
Will know over the next couple of months whether they work or not!!

New age WRX heads have smaller ports than STi 5/6 and UK 99/00. Maybe by porting you could get them similar.

Heads
No comment from me - I'm waiting to see how many are built with which heads and how many of them last and for how long.............. It's not as easy a conversion as you might think.
