[ejsnail]

So im building a motor (ej22 phase 2) that i bought for lesss than hundred bucks. The issue was a bearing i pretty much got it torn apart buti just came across a ad in cl some one is selling 2005 impreza sti heads so i want to know if these will fit if they will fit what kind of issue may i have with those heads on my block? My plan is to boost it im going to get new pistons and rods soon i would like to have this built buy the end of winter.
