I think the wild cams are STi3's, don't think any head difference between STi & RA

Yip i have a set of them lined up. I was just wondering what the lift and duration are on the cams above for these heads. Also if the port size is of any difference.

I know the sti heads have solid lifters and stronger valves and wrx ones hydraulic lifters. Any other difference??
