The Stovebolt Site Forums The Shop Area Engine Shop rocker shaft freeze plugs

I've asked about cleaning my rocker arms here before, but now that I've done that and I have the new 9/16" freeze plugs, what's the best way to install them? They are a very tight fit do I use something and punch them in from the center or try to use the outer rim to punch them in. They look like a bowl and fit about 1/4" down the shaft. I have a 51 GMC 1/2 ton with a 228 engine. The rocker shaft is one piece. Any suggestions.

I have used a deep socket that will fit inside the plug as a driver before. I really think either way you mention should work. Doug
