I have the rcscrews.com kit and it worked fine for me the screws are just a little longer. Also keep on a look out for a new cooling head from acncm.com they should have a colling head out for the evader in the next couple of months. This is just a heads up as there head should be nicer than the stage 2 head. Anyway i will get a pre production one as they are using my engine for measuring and i will post some pics when i get it.
