it runs good i been driving it for couple months.i gone out to back roads and ragged on it sounds smooth doesnt miss or anythin but i no it should run stronger and faster.pre load im not sure i used existing lifters that i had in the motor but i even loosen the to rockers to ensure there up and put air in cylinders and dont hear no air leaking.i really dont no wat the term pre load means and how to check the clearance.but everyone is telling me the pushrods are correct size
