My cam is .398 and 250@.050 Never had an issue breaking in dozens of other cams but.. should I put light break in springs on then switch once its broke in??

I've been using GM EOS for 40 years and have never had a cam lose a lobe, but again, I've never run the spring pressures and lobe profiles like this either.
