2000 beetle head bolts (1.8 turbo)
 

Anybody tell me what size the head bolts are on this engine??Aren't they "triple squares" like used on the drive axles? Thanks!!! New info, to those that have browsed but not replied for whatever reason, i have learned since posting that they are called "polydrives". ..as Paul harvey would say; "Now we know..the rest..of the story".
