The gasket should be marked "FRONT". As stated it will be the front and facing up, so you can read it while laying on the block. Some holes do get blocked in some applications.

That LOOKS like the correct gasket for a 351 c the small tab sits on the LOWER FRONT CORNER ON BOTH SIDES OF THE MOTOR..The last Picture of the gaskets laid out is how they go you can see the small tabs..I TOOK THE PICTURE AS IF I WAS SITTING IN THE CAR LOOKING OUT THE FRONT

Not true..The problem with that is ONE will read front ..while facing UP.. the other will be be facing DOWN SO YOU WILL NOT SEE IT MARKED FRONT..EASIEST WAY IS BY THE SMALL TABS

Absolutely correct, one faces up and the other faces down-front will be marked.

Pulled heads and did find passenger side on wrong. After correcting took and extra gallon of coolant to fill and THUMPING GONE. Just took a year to convince myself because never ran hot.. On to next concern.

Congrats on finding the problem! I bet that was a relief after all the extra work.
