Either Stock STI or Cosworth for head gaskets. As for head studs, ARP. However, you should consult with your builder first.

Use the head gasket for the block.

^^^NO USE THE HEAD GSKT FOR THAT YEAR HEAD,the block coolant passages on the ej257 and ej255 blocks are pretty much all the same and the 08wrx came with a ej255 block with d25 heads.If you pushed out a stock head gskt it was probably due to detonation.I hope this helps and just ask if you need any more info or help.

My mistake. I thought the 08 had the 2.0.
