I'm to the point on my project where I need to weld in my mount brackets. Problem is I don't know what the stock tilt on a D16Z6 is. If anyone has a z6/y8/y7 head mounted in their car and a few minutes, could you take a measurement for me? Seems the easiest way is to get a level on the VC and get a distance to a point like in the pic below. Just let me know where you measured from and the distance so I can duplicate it. Thanks!

 

Added y8/y7 since I was told they use the same VC.

 

I think its the oil pan you should be more concerned about... not the valve cover.

 

If the valve cover is correct, the oil pan will be correct. It's easier and quicker for someone to get measurements off the VC instead of laying on the ground and getting it off the oil pan.
