just enough to be dangerous!

Hi Chad,
I talked to our QC guy at the fastner company we represent.
We need a plating expert to chime in.....
My understanding is that to have parts plated, they are first cleaned with HCL. This lets Hydrogen get into the steel.
The parts must be baked after plating to remove the Hydrogen. The baking must be done within a specified timeline.
He also told me that as the hardness increases, the parts are MORE suseptable to embrittlement. Anything over Rc30 needs to be baked. I suspect the studs are much harder than that.
I'm not saying that you have ruined your studs, but depending on the plating shop and their quaility control?????

Maybe I'm all wet as well???

I don't mean to come off a a jerk, just find this stuff interesting, as I am planning a similar rebuild, and love the look of your engine, but would hate to see you have a problem that could cause a failure.
