v5/6 uk heads/cams vs v5/6 sti heads/cams
Can someone explain the difference between these. I want to know whats better, I have a uk turbo, is it worth changing the heads to sti? Do the sti heads give more low end power? Also if I wanted to change the heads over would I need to change wiring loom or anything like that? And would it need a map tweak after. All help and advice is appreciated

STI Heads are better (can take a bit more power)
I'm not sure what the actual differences are (lift, revs etc probably)
Wiring loom will be fine.. Remap.. I would think so.
Why do you want to change the heads??.. UK ones will be good for at least 400+

STi heads have 'better' camshafts with greater lift I think so can rev higher than UK cams ?
The valve shims and buckets are different as well (under bucket shims on STi, over bucket shims on UK) to cope with higher RPM limit I presume ?
I don't know if the valves are any bigger but they do appear to have different numbers stamped on them compared to the UK ones ?
