I dont know what the name is in english ..german means "Froststopfen"..this are the parts they came 3 litle round pieces left and right side in the block for water stopping ! (hope you understand this !!)..the same pieces comes in the heads from engine (buick only?)..the dealer here in germany dont have/know this parts !..where I can get this ?..or can I take another one ?

I guess you mean the "freeze plugs"? (I see the first 5 letters spell frost, which is close to freeze). These are the brass(?) plugs that pop out in case the engine temperature gets so cold that the coolant gets too cold and starts to freeze, these plugs will pop out to hopefully prevent the block from cracking.

Anyhow, they are commonly available in the US and I would be surprised if they are not availble there, although you will probably have to measure the diameter and order them according to diameter instead of ordering them for a Buick.

right !! ..freeze plugs !! ..for the block I have new freeze plugs but our dealers here in germany dont know the frezze plugs for the cylinderheads ..there is one hole at frontside and one at rearside from the head !..I wonder why nobody knows this here in germany..every overhaul from an engine we will change this freeze plugs to brass plugs !

this are my heads..for this holes I nedd the plugs !
