11 out of the 12 bolts I got were good. The 12th bolt's threads were messed up right out of the box. So I couldn't use it. Was very inconvenient and good thing I had one of the old bolts to replace.

THESE ARE NOT SOHC BOLTS these are dohc bolts the sohc bolts are m11x1.25 190mm dohc are m11x1.25 167mm these bolts are too short for sohc motors and strip the block. The short block is ruined the threads pulled right out of the block after doing the torque sequence from Subaru. If you need sohc bolts make sure you get the right length or you’ll be screwed like I am now.
