Comp 929's will work.
At near 500 hours, you should be thinking
about new lifters too.
Two years ago, I installed new springs
in a pair of 96' Hp 500's that had 400 hrs on them
.......a year later, a lifter broke, wiping out the cam.
Tore the other engine down, and it
had a lifter ready to fail.
The lifters are a crane p/n 13532-16
