So I bought the subaru with the heads already off. I have long and short bolts. Was told short go in the middle. Which holes are considered middle? Anybody have a picture or drawing? Was told not to put short bolt in long bolt hole because it will strip.trying to do this once and right the first time. Thanks in advance

Look at the heads and it's abundantly clear which ones go where. 

 

It's not the block holes that make the difference, it's the heads.  Look at them and it's as clear as air. 

 

There are two different height holes in the heads.  The longer bolts go in the taller holes and the shorter bolts go in the shorter holes.

 

 

And yes it's the lower middle row so to speak. 

Thanks for the prompt response. I do see what you are saying now.
