Before I put this head on the engine I am removing the outer spring to look at the seal.  Can someone tell me what I am looking at here?  This rebuilt head has never been installed, but been sitting for several years.  I remember the round rubber disc seals that I bought for this, but are they supposed to flatten out in the cup around the valve stem like this?<div id="yMail_cursorElementTracker_1585954822356">Mike MacLean<div class="yahoo-compose-assist-image-card ymail-android-inline-img-container ymail-card" contenteditable="false"><img id="ymail_attachmentId24153" class="inline-image-global inlined-image-cid-5478c434-ad1c-4d8f-a576-ee8de846f205" src="cid:5478c434-ad1c-4d8f-a576-ee8de846f205" style="width:100%;max-width:800px;"><br></div><br><br><br><div id="ymail_android_signature"><a id="ymail_android_signature_link" href="https://go.onelink.me/107872968?pid=InProduct&c=Global_Internal_YGrowth_AndroidEmailSig__AndroidUsers&af_wl=ym&af_sub1=Internal&af_sub2=Global_YGrowth&af_sub3=EmailSignature">Sent from AT&T Yahoo Mail on Android</a></div></div>
