Ok I changed my stock rockers out for some harland sharps because they say with AFRs the guides are bronze and will wear out with stockers
it seems to have more valve train noise is this just the way they are? I checked my preload and its about the same as the stock ones
thanks for any info! I did a search and found nothing on the characteristic of the rockers
Who is they and how does the HS rocker arm reduce side loading on the valve stems? The only valve train component you replaced was the rocker arms and you have increased valve train noise?

"They" would be any head mfg. that uses bronze wall guides. The sliding effect of the stock rocker will side load the guides causing excessive wear.
AFAIK, All of them recommend using full roller rockers to eliminate the problem.
Before installation, did you set the geometry (wipe) of the rockers or just bolt them in? If the geometry is off, the result could be more side loading which then defeats the intent of using them.
