I would spend the $4k on something stronger. celtic motorsports here in Orange County has a fully built closed deck short block for $3,750. You could then port your heads, with new cams and valves and be good for about 700whp (on the block). Even if you don't do the extra steps you're still getting reassurance and safety from a closed deck for a good price. http://www.ebay.com/itm/Subaru-Rebuilt-Closed-Deck-Shortblock-EJ257-2-5L-STi-Block-Forged-Pistons-Rods-/330735882670 Vader from NASIOC is running a closed deck at 900whp..
