How long did you run the car for after you changed the lifters? Sometimes it can take a little bit more time to get them running ok. Is the oil in the engine clean? If not, it might be worth changing again and see?

please read first post new oil and filter, have had engine running for several days at various revs no change believe i have oil gallery blockage any ideas on how to unblock without stripping engine, misfire was loose inlet manifold bolts new inlet manifold gasket fixed that problem

Is the oil filter tight enough? Oil not too thin? Pushrods not blocked up? Could try to top pushrods up with oil to get them sucking, with a syringe, say. Have used Nulon for noisy lifters (blue coloured stuff) worked great in my old wb, cheers

No pushrods in overhead can motors.

Take rocker cover off, and belt them with a rubber mallet, if that doesn't fix the problem, then its probably electrical

try using a good quality oil 10/40 grade any thicker and oil cannot get to lifters
