Jd 757 engine replacement

[agr682]

I have a 2005 JD 757 (1300 hrs) that keeps overheating and warping the aluminum heads. I have had them replaced a few times and it is getting where i am contemplating replacing the engine. What is the best engine to replace it with? In your guys opinion will I have the same issues with another kawasaki of that model or have they fixed the fins getting clogged with grass and debris on that engine. My other thought is could I upgrade it to a 27 HP or something liquid cooled to without too much modification. Is it worth replacing at all? any thought or experiences would be appreciated.

They can't fix the problem. It's on the seat.
