I bought a clean 02 wrx from a friend at work. Has a little work done; intake, catback, boost gauge. However, the tensioner for the timing belt pooped. I only paid $900 for it and I would like to rebuild the heads. I work for Toyota manufacturing, so wrenching isn't a big deal, but, I'm not familiar with Subaru. Any tips or tricks, advice, etc. for this undertaking would be appreciated. I will make a DIY on head rebuilds for the greater good of the community. Too many folks just junking engines when rebuilding heads isn't too big of an endeavor.
