Thanks for the great responses, guys. I've ordered the gasket set, the oil filler seal, and 15 grommets. Hopefully, I can get this one right - it's my first time getting into the engine bay under such circumstances. I'll be going to get the Permatex Red Hi-Temp RTV tomorrow.
One concern of mine was the variation of brands offered by Pelican Parts (I chose them over BavAuto because they got down to brand specificity). I picked the Victor Reinz brand parts - what's the general consensus about the quality of that brand? I've seen anything from "it's great, it's OEM" to "15k later, I had to do the job again."
