Question about oil plugs

I have a 406 sbc and I forgot to put all the oil plugs in which i nitce when i tried to prime the engine and couldn't get more then 8 pounds of oil pressure. I forgot the ones behind the timing chain. Everything I've read on here people talk about the 2 galley plugs and I have three holes just like on the back of the block. Do I just plug 2 of them(the number of plugs left in my kit)?I'm guessing no. It seems like that would still be a big oil leak inside my engine. Any help of references to discussions about this would be very helpful. Thanks!!

Every hole needs a plug. I can't remember how many plugs there are, but it's at least 8. 3 on the back of the block, 3 on the front, one near the rear main bearing cap, one on the driverside rear of block where the deck surface is (the cylinder head has to be removed to install this one), and there might be one or above the oil filter mount on the outside of the block. These are thread in plugs.
