Thanks for the tip - I end up driving plug just below the edge of the chamfer. Then I installed front cam thrust plate. I checked amount of in-out play by moving camshaft until it hit the rear plug. A dial gauge mounted on a magnetic base established amount of total play before cam sprocket was installed. Camshaft sprocket thrust surface keeps cam from moving into the block and thrust plate keeps cam shaft from moving out of the block. A very simple, but effective arrangement! It looks like I have about 25 to 30 mil clearance between rear plug and end of the camshaft. I'll have to double check tomorrow.
