I have the source heads, rockers and shafts on my convert and did not have ANY trouble with them. I disassembled the heads when I got them and the only thing I changed was the locks to a set of comp machined locks, I have about 6000 miles on the combo and drive the car almost every day. usually spinning it to 5800 rpms at least once per drive
