What do you folks think? Are the aluminum manifolds and risers (about
$100 more than the iron ones) worth a try? Has anyone here ever used
aluminum manifolds and risers on a raw-water-cooled inboard?

Should I just stick with the crap-iron stuff and get used to the idea of
replacing them every 6 years?

Thanks for any information or advice.
