I used 1.8:1 Harland-Sharp rocker arms in my amateur road race GTO that would see 7,000 RPM. No issues at all.

Some after market rocker arms can tap the valve covers, so keep that clearance concern in mind when you select a set.

Y'all keep em coming! Especially any input on Harland sharps
just a side note, i turn 7100-7300 now and have been for quite sometime on stock trunion upgraded rockers, though i check them periodically i yet to find a issue with them! i personally feel safe with them, and they are light.
