Canadian Members - any engine shops in the GTA that do sonic cleaning??

i'm looking for an engine shop in the gta that uses a sonic cleaner to clean their parts. and would anyone know if they can clean plastic intakes or not? i can't seem to get into all the nooks and crannies and i want it cleaned thoroughly inside and out. thanks.

Stefco? Ronnies still at it eh? Shit I thought he packed it up years ago when he closed his shop on Ruggles. Anyways he built some good stuff back in the day.

Wheres he at nowadays?

He is on 48 just south of Stouffville side rd. He did my shortblock last year.
I had a hard time finding anyone that would do a 4 bolt splayed conversion on my 383 LT1.
