Thanks Lynn.

That is one spot I have not checked with the stethoscope.

Question: can you hear an exhaust leak with a stethoscope? I have listened to the exhaust from above with it but don’t hear anything untoward...

I should say that I didn’t hear any noises during the run in or dyno tuning, so the potential exsists that this pesky sound is an accessory bolted on afterward.

When the lifters are on the base circle I can spin the pushrods which I gather is a good sign. At the same time the rocker can be pushed side to side making the exact same sound I don’t like..... so far my most likely root cause is that the rockers and pivots make this much noise naturally and it is normal. TBD.

The original pivots are aluminum (by memory) but this CC set up is all hard steel (possibly louder due to steel on steel vs steel on aluminum?)

Moving forward each day!!

PS: we are making a date with the Stagers for a first cruise but holidays are getting in the way.... it may be August before we go for ice cream..... this is letting me sort out issues anyways.
