eliongater 718 Report post Posted June 21, 2016 Hi guys. I'm making a hybrid m30. A m30b34 block with a b35 head on it. I'm not sure what head gasket to buy though. The 1.72mm or 2.07mm one. I've tried searching, but I've only been able to find turbo applications (this is stock NA). Thanks Quote Share this post Link to post Share on other sites
User Name 19 Report post Posted June 26, 2016 Do you have any of the links to the headgaskets your looking at?? I would personally suggest you could do with either if they are the correct kit, You can always work out if it will change your compression etc quite simply with online calculators. thicker = larger compression chamber thinner = smaller compression chamber Quote Share this post Link to post Share on other sites

What are the advantages / disadvantages? Quote Share this post Link to post Share on other sites
