Unfortunately? I LOOK for Gates belts when changing belts in my Toyotas!
I had a Tercel (Yeah, I know there's a difference between a 1.5L 100HP
motor and a 7M-GE...) and replaced the belt with 80K on it, and it
looked NEW! Same thing with an '83 Tercel AWD Wagon I had a couple years
ago. I think for the aftermarket belts, the Gates are the best choice.

And, 80K is kind of pushing the envelope for any belt. I have gone 120K
with Toyota belts on my Corolla GTS...good thing it's a N-I engine!
(Basically the same as the 7M-GE minus 2 cylinders...).

And how did you trash the valves? Were you cranking or something? The
4A-GE and 7M-GE are variants of the same design, which is a N-I cleared
head. You must have had some serious valve float happening to trash the
valves on one of these Yamaha engines!
