Some interesting parts have magically appeared in my garage over the past 2 weeks ....

This is a small sample, does anyone recognize the 2 different headers?

 

This is a clutch I took off a rebuilt motor I am toying with, (more on that later), am I right that it is a centerforce II?

Yes, I believe that is a center force clutch but I don't know which one

The one on the bottom looks like a Datsun Comp NLA  equal length header.

I concur on the clutch, looks like the typical Centerforce design with the inertia weights to increase clamping pressure as engine speed increases. I've not seen a friction disc with two different friction surfaces before though. 

Can't even hazard a guess on the pipes, but other than the thin flange (I see it has blocks welded to allow for flat clamping pressure though), I like it. What size are the primaries and the outlets? Square or round ports?

Yes on the Centerforce. Gold is stage 1 and orange/red is stage II 

Thanks for the helpful replies.   I'll take a closer look at the headers and report back....
