replacement zz3/4 valve springs
I'm having to replace my valvesprings on my engine after the #7 exhaust spring let go and bent the pushrod. I'm trying to figure out what springs to replace the zz3 orange springs with? I have a zz4 cam installed also.

Are the heads stock or can you fit a bigger spring? Comp 918's would be a nice setup or the 1.550" 986's. Wouldn't have to worry about breaking them
