i did they told me this kit fem mhp 126 6022 but they said they dont know if it will be even with the deck. what other kits have 20 othe top

Go look at your summit magazine and, my suggestion is call summit and ask them the same question you asked techinspector1. I dont mean to be rude but even so, tech, knows an awfol lot about compression ratio's and other important things on the topic in which you are posting upon but, he probably has not studied the pistion kits that Summit Racing Equipment sells.

they told me to get this kit fem mhp 126 6022 but i dont know has any one ever used there kits
