Knowing that the head of the motor is aluminum, how would I get parts of the head gasket off? You can't use any metal on the surface and the plastic scrappers are pretty much useless.

I have used Permatex gasket remover for this purpose; chemical stuff that was quite effective (spray on, let sit and after a while a plastic scraper should get the remnants right off). Sort of like paint stripper, but specially made for gaskets.

CJ, No problem using metal removing head gaskets,and on Aluninuim ,been doing it for years,
Buy a new scraper i have a Wilde USA brand, this is what you do,.
You carefully purposely blunt the cutting edge of your scraper,about the same as a really blunt knife,
with a smooth file,and also the end edges of the scraper.
THen it works really well,no problem at all, over the years i did 3 Alfas, 1 etype Jaguar,2 Porsche, and alot of american
cars, i use a Little brake clean doing it,as it evaporates and cleans while doing the job.

If your head is going to the machine shop, they will soak it in a hot tank and it will come out clean and looking new.

I only clean one enough to be able to use my straight edge on it to see if it's flat or not. Very few ever are.

Thanks everyone for the suggestions. What I plan on is soaking it with CRC gasket cleaner and then a sanding block with Emery cloth around it. One stroke around then repeat it until I can get no light under the straight edge.
