legacylee Posted April 25, 2017 Share Posted April 25, 2017 I bought a new short block and my heads are bad. So i found some heads from a 06 wrx single avcs. Will these work on my 05 legacy gt short block. After researching it looks like they will work, but id like some confirmation. my eyes are burning from reading to much.

I believe those are D25 heads, your stock heads are B25. Both will work, but they create slightly different compression ratios. I believe you need a tune for the D25 heads.
