Solstice! Car starts to run rough after hitting the gas, intermittently.

Regarding the tangent, yes, an ill-fitting dipstick can be the cause of a vacuum leak. Pulling out the dipstick is a way mechanics can figure out if the car is suffering from unmetered air/vacuum ...

Removing head while maintaining timing chain tension & position

I would use wire (welding rod is a good candidate) or small springs to "hook" the chain either side - obviously the top part stays loose but the bottom part around the lower sprocket stays firmly in ...
