Hi all, been lurking about for a while now reading about the cam chain issues. Mine is due this weekend, and I plan on having the verslavy mod fabricated by a machinist tomorrow. Although I bought a chain, tensioner assembly, guide, tensioner, and all the necessary gaskets, I am hoping that I can do this easy fix, instead of getting elbow deep in this.
I am sorry for rehashing old isues but I read somewhere on here, but for the life of me cannot find it now, What is the adjuster assembly plunger made of? What type of metal? While speaking to the machinist on the phone, he asked me if it had magnesium in it? I felt like a dork not knowing.... He said he will probably know when he sees it, but for me to try to find out for sure.

Also, what are the torque specs for the crankcase cover and the exhaust header when I re assemble?

I really appreciate it guys.  I seem to be not very good with the search feature here.
I am not much of a wrencher myself, but think I may be able to slide along knowing I have this site for information.

The housing is aluminum and the plunger is case hardened cold roll steel as far as I know.
