I don't believe the Grodin rods require block clearnancing to fit in a 2.0. I do think they would be better suited to a 2.14 due to the weight and the larger bores, less stroke and better rod ratio. The biggest problem with aluminum rods is that they fail due to the inertial loads on them. The compressive and tensile loads are enough that they have a relatively short effective life span before they should be replaced. Titanium is better as is 4130 because they do not fatigue in the same way that the aluminum rods do. Aluminum is not a good solution for a street car unless you don't mind swapping your rods every season.
