Awesome pics, thanks! :2tup:
I gingerly used a brass wire wheel on a drill last time I had a tough gasket. That was on an aluminum transmission case. Worked pretty well.
I did a search on the spray gasket removers, not sure about how I feel about them though based on the reviews:

Not enough reviews to really get a feel for how effective they are. In the negative reviews, in the last one in the link, one guy said that PB Blaster works well as does Carb Cleaner which he links to. But I can't vouch for that personally.

A lot of folks in a Jeep forum recommended the roloc system which is basically a fiber disk on a grinder with the caution that this is not to be used where the dust could get into the bearings. Based on my experience with the wire wheel, I would guess this would work very well. Maybe less messy than having to wipe / scrape goopy gasket material off.

I know that at one of our local (ha! 30 miles away) tool stores, they had a bunch of fiber wheels for like $1 each plus the adapter for $2-3. I would probably try to avoid the high speed grinders or the like unless you know what you are doing and have good control.
