this is nothing to do with the P5, but skyline you just mentioned "head shims". I still have the HB .26 engine, and i have noticed when i take the head off, there is only the big silver plate that the glo-plug screws into, (no shims???). Is this normal on some engines or are they missing???.I can't possibly think i have lost them when taking off the head, in the past!!!
I honestly don't know. every motor is different. Some need shims- some don't- to aquire the right head clearance. I'm not too familair with the HB .26's. Sorry
