1.6s, this may be too cheap

I ran a set of chinese roller rockers, worked great & lasted a few years shifting @7000+/-rpm.
No failure/damage, just had too much side clearance at one point and 1 of the rockers needle bearings were wearing the race.

I'm thinking on having them rebuilt by gary at rocker arm specialties, or just buying a new set-120 vs 200$ er something like that..
