Biggest mistake ever- lunati cams

My neighbor build motors for sprint cars and put that same cam in a Chevy for his son with both springs installed and it runs great.
The machinst builds lots of motors with lunati cams He used to build motors for Mike Dunn before he went into nhra. He said it's a waste of time and I realize that it could potentially cause a problem, but, I just don't see it happening . I have broken in larger cams with dual springs with no issues so unless there is something about lunati cams that causes that issue to happen, I can't see any reason why I should be concerned. I always get nervous while breaking in a motor and really, anything can go wrong and usually does right away. It is important to make sure it is primed, the right oil, and fuel line and bowls are full. Timing light ready and minimal cranking. Watch the oil psi and tach. I think it will fire within 2 revolutions. I will follow the suggested run in process and I guess I will find out if it works or not. My dad used to always say, what your head don't know, your *** will feel but in this case I am using information from reputable mechanics. Worse comes to worse, I have a .508 purple shaft and lifters sitting on the shelf for backup. In all reality, you could use 1 spring, break in then go to install the 2nd one and a keeper pops right down an oiling hole or somewhere. Or install 2nd spring and lobe wipes out anyway. There is always a chance anything could happen. Running with 1 spring isn't lessening much. If it was a big solid lift with massive spring psi, I would use break in springs and swap em but this is .494-.513. that's slightly more than stock.
