Just got back from a week in the SF Bay Area so not much work done. Before I left, installed the heads. Today, I was going to get the rocker boxes and new adjustable pushrods and pushrod covers installed. But, found that I was missing an o-ring for the covers. Always something. I'll see if I can did a similar one up at an auto parts store here. Else it's a call to Nallins or Zippers to get an o-ring. My guess is that I can find one here.
