take a picture of the chain rail and post it here.
also, look at the thread on 2mm lift vs cam mark and do a quick and dirty chain stretch check. you may not need a chain. or you may need all the rails changed. the chain may already have an offset key in there, so after you check the alignment marks pop the cam bolt out, and look at the key.
