Is it true that this engine has Chevy hydraulic valve lifters and zero valve lash? Thank you, Don B.

It is true, these engines have hydraulic lifters similar to chev and they run preload on the lifters. Ryan

Ryan, Thank you for your reply. Could you explain preload of the lifters, as of all the engine I have built had solid lifters? Thank you, Don B.

The engine still has pushrods but they sit on a piece inside the lifter that rides on a plunger that is held up by oil pressure
