not likely, if the rev limiter is removed then it most definitely probably overreved and threw the rocker. Like I said, pretty easy fix man. They can check cam timing with the valve cover off to make sure its good but not likely to skip timing. SR's are not known for that unless your tensioner is very bad and weak. Easy to check, put at tdc with #1 cam lobes facing away from each other, dowell pin on exhaust should be pointing at 12 oclock, dowel on intake at 10 oclock, 20 chain link pins between the dots on the gears. That simple.
