sr20det head assembly questions

[fenderguitarist]

I wasn't paying attention when I disassembled the head on how everything went back together, but I did keep everything organized, so the shims won't be wrong. I can't figure out which way they go in, does the rocker guides on the intake side go towards the front and exhaust vice versa?
I also lost the spacer that goes in-between the bolt and exhaust cam, any one know a part number for it or anything that's compatible for other engines?

can anyone help me out?

I cant remember exactly but look at the rocker arm to tell which shim is at the front. They should be different and the guide will only sit on one of the ends.

The guide only 'fits' on one side of the rocker, so you'll which side slides into the guide.
