Anyone have or know a source for a new or good used head for a volvo
penta AQ131a engine. This is a four cylinder gas engine. I am not
sure if the head is interchangeable with any other models? My engine
is out of a 1986 bayliner.

I had an exhaust valve fail and ruined the head and #4 piston.

Any help would be appreciated. Other wise I may have a source for
parts for someone else.

I am in the area of Portland Oregon. If anyone knows of any good
salvage yards in the area that may have this engine or boat, Please let
me know.
