I had the Machine Shop unload the heads and give them to me and I commenced two doing my first Home Port job.. with some tips from my machine shop opened up the bowl area and smooth out the exhaust. I paid them for two hours of Port work on top of that and then they put the 202 in.. so I really never did get to see without the valves and what their work look like.. (I should this winter when I put the less-expensive Speedmasters in) I also took off the 273 rockers and put in Hughes 1.6:1 rollers...
