So long as geometry is right[rocker ratio]. There is no need to, remember you tighten them up on lifters pluss 3/4 of a turn for the lifters to be at zero lash.On hydraulic lifters...

Thanks for the replies,

It is Hydraulic cam, but I'm not sure if they are bolt on's on adjustable, so I'm going to speak to the guy that built the engine.
