Timing/ Tuning a '73 318

I messed up and did not do a compression test before and I have not done one since. I should elaborate a bit on what happened. It overheated and did not actually blow a head gasket, It had water in the oil but it was from an incorrectly installed intake. The main bearings were bad but they did not turn. I looked at the rod bearings and they appeared to be good so they didn't get changed. And thank you for the warm welcome!

Also I did some reading in my carb book and it said the passenger side was for emissions controlled motors. Go ahead and and change it anyway?

Thanks I really appreciate the help!
