I'm worry that the machine shop didn't replace the valve steam seals.


Sounds just like valve guide seals. A bit too much oil will not make it smoke, but may mean the crank rotating through the extra oil will cause the oil to foam, reducing lubrication. You need to drain out the extra oil ASAP and take your truck back to the shop that built your heads <img src="/forums/images/graemlins/kewl.gif" alt="" /> Good luck
