I have two Volvo AQ131D motors that need new heads. The back exhaust port corroded out on both. What are my alternatives for replacement heads, besides buy two new Volvo Penta heads at over $3000 a piece. The stampings on the head are Volvo 100531. Thank you!!!

Re: AQ131D need new heads

Same thing happend to my aq131d...Mine must have been a later model though as I have a metal ring inside the number 4 exh port. I have mine at a machine shop and they are re milling it. Should be about 200 for the job... There is also a place out there, if you do a google search that sells new heads with the cam for 552 a piece.
