Can anyone tell, just by looking, if these are the excellent c.500bhp-capable STI Version 3 heads (and not the lesser performing STi Version 2 ones):-

Sti heads on eBay (end time 18-Aug-09 22:10:04 BST)

Thanks in advance.

 

Email him for better pics of the valve codes and cams - quick glance shows Version 3~4 heads (shape of spark plug hole) and recessed top spring cap to take STi Inner Shim .

the spark plug hole shape is different to my STI version 2

 

Sti version 2 has square plug holes and the newer versions will have the oval type.

Although looking at those pics which ain;t too good it looks like the buckets to the right have over bucket shims (this may just be due to the dark outline on the bucket or camera flash). But again this cannot be guaranteed until the seller takes some pics and sends them to you.

Cheers lads.

Baly, should the STi v.3 heads have the shims UNDER buckets, then?

 

Yes sti under bucket.
As said not wonderful pics but look more like v3 wrx or uk

 

How do v.3 (and v.4) WRX/UK/RoW heads compare to the comparable MY STi ones, performance-wise? Are the STi ones fitted with cams with more aggressive profiles and bigger valves, etc., etc....?

 

Have a pal with a nice set for sale get intouch if you intrested
