Metallic scraping noise in 90 SPG exhaust manifold(?)

Hey all, while driving around the other day I noticed a disturbing noise coming from my 90 SPG. It's a sort of metallic, scraping sound. Opening up the hood, it seems loudest from the exhaust manifold area, but somehow it also almost seems like it's coming from the oil compressor way over on the other side. I tried poking around with a vacuum hose to isolate the noise but it's hard to pin down.
Here's a recording, not very hi-fi unfortunately: https://www.dropbox.com/s/h2dwkjiwxppbvq0/Saab%20Noise.m4a?dl=0
It sounds like metal on metal, like something's not lubricated properly. The frequency definitely goes up with the engine RPM. The most recent work was about a month ago: had the water pump replaced, torqued down the cylinder head, replaced the valve cover gasket.
Not really too interested in starting or driving the thing while this is happening. Any ideas?
