Make sure the intake pushrods don't have interference with the heads. I had to have mine clearanced on the outside of the intake port casting.
Manton can sell you some checking pushrods. Put them in, adjust them and send it back to them . They will make you a nice set.
Be careful not to float the valves in the motor. Mine floated at 5700 rpm and resulted in some nasty valve train harmonics that ate up some valve train parts. I ended up going solid roller, so I could run more spring pressure. Do you know what seat pressure they set your heads up with?.
