A question about intakes

So I tore into the engine yesterday and have discovered a few things. First this is a 66 block. The intake has not been modified so it must be the Ld4b intake. The engine has definitely been rebuilt. You can still clearly see the hone marks on the cylinders. The heads look to have been done and it has a brand new cam in it. It appears the lifters are toast from condensation as they were stuck and some are collapsed. I got them free and will be replacing them. The cylinders are not rusted like I thought they might be but currently it's still stuck. Haven't attached a bar to the crank yet to really force it. Going to drain the oil shortly and pull the timing cover and pan to inspect there as well. Definitely got my money's worth though. Hopefully a new set of lifters and a set of Haley's and seals once I free it up and we'll be good to go.

Have to flush the block of course. The only thing I noticed is that they never cut the ridge of the cylinders but that shouldn't be an issue as it's less than it looks.
