It depends on which engine he's working on because the M130 is self locking so you only have to adjust the one nut and they can be really really tight.
Also if he is working on the M130 I guess you could use the home made valve spring compressor tool described in the Haynes manual and I think you would have to remove the camshaft to use it otherwise I think you need the camshaft for leverage if you are using the correct and expensive tool.
