Engine smoking

What do you guys think the problem is with my engine.
I bought this 73 454 that was supposed to be OK a while back. Put my newly rebuilt (new guides and new teflon seals) 72 402 heads on it and yesterday I started it for the first time. It ran good but smoked from the left exhaust pipe. Then suddenly it stárted to run on 7 cylinders and a mecanical noise came on. I took the engine out of the truck and found a very oily exhaust port on #5 cylinder. Is it a bad oil ring/piston ring or what do you guys think?
Thanks in advance.
Mats.
