I have a freshly built Ford FE 428, and I think I have a varnished/sticky hydraulic roller lifter (they sat for 2-years before the motor was built). Before I pull the intake off and lifters out, I would like to try Sea Foam to clean them. I have only 400 miles on the build. Any concerns about ring seating or other potential issues with a fresh motor? Also, would I be OK to add the recommended amount directly on to the tops of the lifters, through the top of the head/intake? Thanks.
