Planned on putting rings in my 46 burb and going over the head. Used the casting numbers on the engine (3835309) to order my rings. I know 48 & 49 #s. When I opened the package the 2 pressure rings were different sizes. The rings on my piston are the same size, and the same size as the largest of the 2 in the box. Is the year the difference. I'm lost as I don't want to order something wrong again (at $50 or $60 a pop). Taking the head to the machine shop tomorrow and will show them. Maybe they can give me some answers. Thought you folks might have some insight
Thanks
Jim
