yea its a head gasket... i think the vw told all vw mech's to remove them or leave them out when doing rebuilds. They can also be used as shims to decrease the compression ratio, in which case they are better used between the crankcase and the cylinder...

woops, meant decrease...

few good threads on cylinder to head sealing on the shoptalk forums, i assume t4 procedures would apply to t1 engines...

My 1500 single port engine has the shims between the cylinders and the heads.
it was already 1600cc when I bought it, and i left the shims there,,,

I think early 1200s had them as standard plus I've heard they were used by shoddy engine rebuilders in the past to save any extra work for sealing purposes.

You will have to work out the compression ratio, but more than likely the old heads have been machined too much and thats why the spacers were in there too reduce the compression ratio

Do the spacers fit on top of the barrel or do they fit on the outside of the barrel this will say werther they are to reduce the compression or if they are old style gaskets

Are they brand new heads you have ????

I read it on FACEBOOK so it must be true

the rings are inside the combustion chamber which i think would mean they are on top of the barrel.i have had the bottom end rebuilt and the old heads are cracked so i will be buying brand new ones.

It would be best to work out the compression ratio

so if the heads are craked and you are getting new one they should lip inside the new head
if you look at your old ones and the new ones you should be able to tell if you need them
