You need to check your rocker arm geometry as well as checking for coil bind and clearance to the guide. Should be fine with the lift you have, but obviously something is wrong. Do you have 1.6 rockers? That could be your problem. While a lot of people run them, I believe they are a crutch for the wrong cam.
