I believe they do the 8.5:1 based on the clio headgasket.

Dan right. Standard gasket.

Depends also on if the block has been decked or head skimmed as those will raise CR, Also if the chamber has been worked it will lower the CR, measuring is the only way to know. The quoted figures are nominal only.
