Hi guys, just a quick question.
I set my valves a few weeks back and i noticed that on some cylinders when both valves are closed some of the rocker arms can move from side to side a little on the rocker shaft (not much but there is definitely movement).

The rocker shaft and arms are set up properly, with the original spacers between each rocker pair and the correct separators on each of the bolts (small, large, small, large, small, if i remember correctly).

Anyway, i was just wondering if this was normal or if i should purchase some extra spaces to make them tight. Would probably reduce some of the engine noise :)

Summit sells this little set, would that do the trick you think?

Thanks, Wilco.
 

once you have the rockers bolted on...you can take a feeler gauge and check the side clearance on them...

then use the shims from the kit to make sure the rocker is centered over the valve.
 
you should try and maintain ±.015 between the rockers and holdowns. Too tight and you will get gaulling on the sides as metals expand.
