No you can't. The TUPY head will still crack, but it's least likely to compared to the original 0331 head. Even the Clearwater head isn't guaranteed not to if taken over 240*. There's a melt tag on the back of them that is a telltale if it has. Your only option now is to find a used TUPY in a junkyard.
