That is a common crack on F heads. Mine has it and yes I had the machine shop put a threaded plug just short of the outside stud between the valves. You are fine as long as that crack doesn't go into either of the central two valve pockets. Check your head above this area. Mine was cracked clear through the intake valve and spark plug hole on # 3. Had to find another head. They also decked both the block and head. You have to use a good thread sealant on the head bolts, and they go into the water jacket anyway, so I wouldn't get too worried. John

There is no oil near here, so you better get the block magnafluxed to figure where the oil came from first before you fix it. I was pressuring the radiator with my crack, but no oil in the antifreeze. Good luck. John
