blox stage 1 camshaft

so i'm getting this camshaft and a skunk 2 intake manifold cheap from a guy that never used them when he bought them. I have a few questions. I cant find a whole lot of information on people that used them. I did run a search on google and came across a thread on dseries.org about it being a copy of skunk 2 stage 1 cam which is no surprise as blox is a copy of skunk 2. anyway, a guy on there shows the lift and duration and it appears to be larger on the intake side than a crower 2 cam and smaller on the exhaust side than a crower 2 cam. is anyone running this cam or know of anyone using it. id rather not hear they are garbage unless you have personal experience with proof of that experience..not being a douche but some people on forums throw bad reputations out rather quick. if it truly is a bad part, i'm all for hearing about why.
thanks guys.
