You should ask them about using BBC rockers, see what they say.

Already called it after the first motor broke. It's the rockers.
Interesting tidbit ... assume for the moment the OP was running the Lunati 712 cam in the ill-fated motor. With 1.7 ratio rockers his lifts were .606"/.623" (I/E). If the rockers were 1.8 ratio, .642"/.660" (I/E). If the cam was the 713 , then .634"/.640" (I/E) w. 1.7 rockers and .671".678" (I/E) w. 1.8 rockers.
