Finishing a 2056 build with new 2L head castings, new WebCam cam, etc. Valve geometry done and SAT, so have custom lenght new Chrome Moly push rods. From all the searches it seems the consensus is zero valve clearance with these push rods and we also installed new genuine 911 swivel feet adjusters.

Can we get a general consensus to confirm ZERO running valve clearance is preferred?

or

IF not what is the recommended clearance?
Thanks
