CU barrel to head gaskets

[e11ie]

Hey
I am looking for new gaskets to sit between the barrels and head before I put the heads back on but there seems to be 3 different thicknesses. Anyone know which I should plump for.....0.7, 1 or 1.2 (1980 CU motor)

Ta, Ellie

Standard is 0.7mm unless the heads have been reworked then thicker gaskets as appropriate

Thank you
Heads have been rebuilt and have solid lifters but stock other than that

As per VWs technical update, you don't use the HG anymore...

You shim the base of the barrel to maintain deck height/piston to head spacing

Also if they're new AMC heads, then they have a step cast into them to replicate the HG thickness
