$550 included a complete valve job and reconditioning of the head and came with 1 year warranty so i guess it is not bad deal.

just picked up the head and trying to installing everything back together and got some questions.

1. head gasket kit I've got is from MB dealer, A104 010 37 20 and realized that exhaust gaskets are different than what I removed as it were all individual gasket and now it came with 2 gaskets and a group of 3 holes... and they are identical but first gasket near cylinder #1 only had one hole on top side but new ones had 3 holes....

2. can someone tell me what these washers and rubber gaskets are for in the pic attached?

3. I remember the chain was somewhat tight when I was removing the exhaust cam sprocket before but now it seems a bit short or too tight so I can't put the sprocket onto the cam.... is there any trick to it?

Thanks
