Crane -10 cam kit

[flashbk2]

I had crane cam kit installed early August and drove it home only to have stock tensioner explode and bend all my exhaust valves. I installed bstockum tensioner and new valves car ran great for 4,000 miles . Ater mini teardown yesterday discovered cam timing is way out but no belt failure(ie missing teeth or shredding) and good tension on cam belt . Before it failed to start symtoms were missing @5-6000 rpm's,then missing @ 4,000 rpm's and finally missing @ 2,000 rpms. This all happened in a 24 hour period . The crane kit comes with much stiffer valve springs.... Is anyone running this setup and are you having any problems ? Post here or email me @jlavaresr@stny.rr.com. Thanks
