My 13B TII is losing compression at the moment and I"m looking for a good shop to get a good rebuild + polishing + mild streetport done on my engine.

I live in Montreal but I don't mind going up to 300KM away from montreal for the rebuild, does anyone have a good place to recommend?

I know Derwin are expert but from what I've heard, they're pretty much booked till september, which is not ideal for me.
