Help what are these holes

[mikemikeremix]

Someone please help me understand if these holes are supposed to be here or not there's one in the opposite side in the back

They look like oil weep holes, so the oil will fall back down into the oil pan.

Techinical term for them on older V8's like yours are "Oil Drain Back Holes".if you lift the spider cage holding the lifters in place,you should find bigger ones that will let you actually see the camshaft.

I have done that way to many times. I also had a scale to weigh all the rings, rods, connector pins, pistons etc... To balance the engine. I would sit with a beer and an air grinder opening up the intake and exhaust ports to match the gasket and smooth out any roughness in the casting. I have one more engine to do for my 68 Mustang. Then no more.

That's one thing that's a big improvement over days gone by,it's a hell'va lot easier to port aluminium heads and plastic intake manifolds then it is to port cast iron heads and intakes,lol. Spent many an hour porting 2 barrel cast iron smallblock intakes for claimer classes,where you were limited to a 2 barrell factory intake manifold,lol
By the time you were done,you could hardly get your fingers unwrapped off the die grinder
