Not the top of the valve covers but the side of them. I have the anderson covers and they are pleanty tall. But, I had to grind this ***** out my rockers to get them to clear in the corners of the vavle covers, and they were hitting a little in the back and i ground them down. But the still hit, only sometimes though. When im coming to a stop "Tang, tang tang," against the covers then it goes away. Ill look to see where next week when i put my new 1.7s on. But now im just guessing ill have to grind the **** out of these two.
