[Roadsters] 1600 tuning issues

[Tim]

I have (as usual) nothing new to add. But, I will echo what others have 
said as well as Paul below. And also add that my running issues got 
worse and worse on my tired 1600 as the exhaust leak at the manifold got 
worse.

Still waiting on my machinist to finish the head on my stroker. One step 
forward, two steps back.....sigh
