Engine Coolant Flow on a 1974 360

Please confirm the path of flow for the engine coolant leaving the cylinder heads on this engine?

I noticed coolant ports at the rear of the heads, but these are blocked off when the intake manifold is installed.

Does all coolant leave the heads at the front coolant ports, then thru intake, thru t-stat, and back to radiator top?

If you want to know everything there is to know about SB cooling(& then some) go here & plan on being there for awhile. www.moparchat.com then scroll down to & click on circle track chat then read Sanborns cooling mods that are in a sticky at the top of the page. Dont be fooled by his "aw shucks" good old boy type of demeanor he is actually one of the countries most knowledgeable SB mopar cooling experts.
