350 Head connection

[cmptech]

I know this is a newbie question however I’m just re-entering the Pontiac world!. Putting back together a 75 Pontiac 350 motor for my sons car, that I received in prices. It has 46/6H heads that have been redone. Can someone please tell me what gets attached the the nipple footing on the rear of the passengers side head? (Picture attached)
Thanks!

Heater core, you may want to invest in the factory service manual for the year of the car.

Engine is a 350. Has a build date of 1975.Have no idea of what it came out of. Engine code is YK. When I try to cross referencing the YK code, I can’t find any information for a 75 YK code 350? Stumped.

Oh wow thanks! This thing is way off.lol!
Came with 46/6H heads valve sizes measured out at 2.77/1.66 brass stem inserts, Cam is 9779068, came with an extra Camshaft 9779066. Intake manifold is 9799078.
It’s 90% put back together. Interesting to see what it’s going to run like with all of the random parts…We’ll see. Thanks for the info!!!

068 should be interesting in a 350. As you may know it was used in the Ram Air III 400, and the 455 HO. Is this an automatic or manual transmission? This link points out it's a good choice.
