TDC and timing chain question

[billetproofcustoms]

OK, confused still about TDC and timing chain relation, my 350 is on a stand right now almost finished with the build, the motor #1 cylinder is at tdc on the compression stroke, dot on the crank cam gear is at 12 o'clock, my question is this, I have been told that in the #1 cylinder TDC compression stroke position, the cam gear dot is actually at 12 o'clock also, otherwise you are 180 degrees out, the next revolution of the crank lines the dots up (cam 6 and crank 12 o'clock) which is TDC for #6 cylinder. (companion cylinder), as it sits right now at #1 TDC compression stroke, where should the dots on my timing chain be? I got this info from the "real fixes real fast" youtube channel, it is video #5 (engine rebuild video) at the end of that video in case any of you need to reference it in order to HELP me out...LOL...please help..
