I an Not much on working on gas air cooled engines but have a late model GX390 Honda that broke a piston. No problem got the block tore down and ordered a block. Also ordered a HEAD KIT. Comes with valves in head , new cam, new head bolts, head dowels , full gasket kit. Here is my question in the package with the 4 head bolts, two head dowels, is one more small cap. It were an old cheve engine it would be the small cap that goes between the top of the valve and the rocker arm. I did not take one off of either valve on the head I removed. Does this cap go on a valve or where does it go. I can get a picture if anyone needs but looks just like a cap to go over a valve, however the rockers are rounded and in the other engine were direct to the valve end. Help e mail is open

I don't know, but suspect if you go ahead and assemble everything, it will be obvious if it's supposed to be there or not.
Do some measuring, comparison between the old and new. Look at the adjustment, if it's supposed to be there, chances are the rocker will not have enough adjustment, or it will be at the limit, be at a strange angle, etc.
If it is a lash cap, it will fit the valve stem exactly, with no interference with the keepers. It will be very hard, with a polished wear surface.
Is there a customer service number to call?

Thanks for all the answers and yes Joe is right , finally gat an answer from Honda, strange but they only cap the exhaust valve and it does fit perfectly. I WAS watching for such when I took the valve cover off. Valves were adjusted with NO rotator , there was evidence that this engine had just been into. Suspect someone just missed it on building this engine. Thanks again for all the answer.
