Yea, and sits on those special O-Ring type gaskets that can't have any contamination before install - "Like oil" - You Clean the head w/mineral spirits before install, any oil contamination will cause NEW gaskets to leak.
The light torque numbers - Reason ? You can't smash the gasket or it won't work. It's suppose to compress and sort of stick to a dry aluminum head. My intakes a little different, it's aluminum and has 3 tightening stages to compress instead of just the two. This doesn't require much torque to accomplish.
Hope that's the answer OP was looking for
- If you want I'll pull the procedure from the service DVD and email to you if you know the year of yor motor.
