Do you mean the hollow dowels around the top corner Head bolts? If so, 2 is fine.  That is how they come from the factory.

I have heard of high HP  turbo builds using 4 or 6, but it isn't necessary for standard engines.  2 is how it's supposed to be. 

 

When I think of "piston pin"  I am thinking of wrist pins.  But those have nothing to do with the heads.

Hey, thanks for the reply!

These are what I'm referring to.

Howdy. New forum member here with a quick question. 

 

Me and my buddy are working on my 97 impreza 2.2 wagon. We're doing head gasket replacement. The thing blew due to low radiator levels. My buddy, who's a mechanic, doesn't have much experience with Subarus and commented on the amount of piston pin bushings on each cylinder head. There were 2 on each head. He said he believes there should be 6 on each. Does that sound right? We're thinking of replacing them and don't want to order more than necessary.

Open to your input

 

(There's a bunch of other stuff we're replacing on the vehicle but this my current curiosity.)

 

Thanks!
