If it happens again I will install the AFM delete plate, cam it with LS7 lifters... Beware even cars with an M6 have AFM lifters on cylinders 1,4,6,7. Right before my lifter collapsed it felt like it was misfiring right up around 6k rpm

Wow sorry to hear about this. I just finished my Magnuson install and reading something like this doesn't give me the warm and fuzzies. Does driving style have any imact here or is this lifter problem just an issue waiting to happen any time?
