91 300d 2.5 turbo
![Question](https://mbworld.org/forums/images/icons/icon5.gif)
I recently bought a 1991 300d (VIN WDBEB28D2MB520843), (Engine model 2.5 L OM602.962 Turbo Diesel I5) and planed the heads.
I was wondering if anyone could point me towards the information regarding what specifications of cylinder head bolts I'm supposed to buy, and the torquing pattern; as I have had poor results finding these out in my search through the service manual.
The bolts said on them "KAMAX 950" but I dont know if thats significant, couldnt find them online.
Also, after planing the heads, is it better to buy a new headgasket or will the old one work?
Any insight is appreciated, thanks in advance.
Edit: Update, apparently two pages forward had the bolt specs I needed, however, there is three different lengths listed (10x80, 10x102, 10x115), so can I choose one type to my preference..? or am I supposed to put certain lengths in certain places? I'm pretty sure they were all the same length when I took them out, but you never know

MBWorld Fanatic!
new head gasket no sense being cheap there.
More cons with using old one then installing new one.

FCPEURO & Pelican Parts have head bolts so they say; maybe call them to dicuss project?
Looks like 3 lengths and they do not have kit for all of them....
Do not forget the bolt Lube to go under shoulder washer of bolts
