What type of compression test should I do guys ie cold hot etc? And how this wrt tuning?

Down the road I plan to lower the compression with different pistons and change the cam. But not right now…

The compression test is best done with a warmed up engine (google is your friend). What is wrt tuning?

I also forgot to mention that my distributor has an adjustable Vacuum Advance Canister, VAC. It's an older Accel for Mopar that I think can add up to 20 degrees.

I'm running an MSD 6AL ignition with my setup and it really helps the idle and my plugs are cleaner.

There is a love/hate relationship here with the MSD ignition. Mine is an older analog version that seems to be less problematic than the newer digital boxes.
