Valve train vibration, smoke

I noticed the oil pan leaking some and I wanted to make sure the strainer area down there was clean so I resealed the oil pan and let it cure. When I went to refill the oil system I only had about two quarts and some used oil. So I added about a quart of it but it was dirtier than I thought. When I drove it was making like a sucking strangling sound when I would go to accelerate and would not really accelerate but would pop a little and resist it. I took off the valve cover and noticed that one of the oil ports was plugged with some sediment from that old oil. I flushed and sea foamed it and and replaced the lifters (hydraulic) and it is back to making good power, but there is still a littler of that sucking sound under acceleration and it smokes at lower rpm and idles a little rough when it warmed up all the way. Also, I can hear some vibration in the valve train when I start it up. Any recommendations?
