I had a long time ago customer call me a few days ago and said that two of the Harland Sharp roller rockers we installed on his engine had the rollers side-load and dig pretty hard into the aluminum. I haven't seen them yet put he ended up pulling the heads and is bringing them here for inspection.
So we may have our first Harland Sharp roller rocker arm failure, will update or start a new thread once I sort all that out.
In any case the list of what I'd use here is getting smaller and smaller by the minute!........
