SBC Rear Cam Plug

[rfmaster]

I am in process of building my 383 engine and one basic question that pop up was the how deep to drive rear cam plug. David Vizard in his "How to rebuild Small block Chevy" states - "Drive the plug in until the edges is just below the chamfer of the face of the block. Spread silicon sealer around the plug-to-block joint". The book shows couple of B&W photos but my copy dates back to 1979 (and has many dog ears!). I am building a roller cam equipped engine that did not exist at the time when he was writing his book.



Does anyone have a better method of making sure that rear cam plug is driven just right to the correct depth.
