Beginning to rebuild b18a1 - engine prep questions

block guard is not the same as the block girdle. girdle bottom, block guard top. the block guard is tapped into the water jacket around the top of the cylinder wall. the square is a good way to tell if the block needs to be decked. in order for the valve job to be accomplished correctly, you'll need to provide the machine shop with your head and valves. whatever valves you're planning on using, give them to the machine shop. hope this helps.
