Is your motor stock? To my knowledge the Twin-Cams in stock form do not have adjustable pushrods to adjust freeplay but I'm no expert on Twin-Cams...

If the clatter goes away after time it is not a cam chain issue...You may be alright so long as the clatter is not permanent!

My rpm dependent clatter turned out to be a loose breather bolt holding the air cleaner backing plate to the engine. Drove me nuts for 1000 miles before finding it was a simple fix. Worth a look.

If it only happens on cold startup, it might be oil pressure related. If you are using one of those ulta-high filtration oil filters, that could be the cause.
