My guess would be if the block has had no anti corrosion in it, I bet when you remove the water pump the hole will be mostly blocked with rusty crud

I've seen a few blocks NA & TT like this from poorly maintained engines

 

Had same symptoms in a customers TT and had to remove the pump to clear the blockage before it would circulate properly, and it had been flushed already

Ahh bummer.

 

Its not a terrible job to do tbh once you get stuck in, as you know the crank bolt can be bit of a pain and another thing I did wrong was to use the wrong length bolt in one of the bypass pipe holes where it bolts into the head and it snapped ...eek.

 

Am pretty sure this is where I bought my last one from :
