best place in town for acid washing cyl. heads?

[Graham_A_M]

Hey guys, I ended up finding an excellent set of used cast iron heads for my buddies 5.0/302 Ford. However being used, there is a decent amount of crud built up that needs cleaning. I'll be porting them myself when I get back into Calgary (yet another reason I need these thoroughly cleaned to make sure there are no metal fillings left in them). So I was wondering who is the best in town for acid washing such parts? Or perhaps bead blasting them. I'm sure there are a few people on here that have experience towards this, so I figured I'd ask here rather then aimlessly call around.
Also, what kind of money is reasonable to expect for getting this done?

I think D&W engines? Pretty positive they do that stuff there
