Disadvantage= valves hitting pistons
^^ Quad and 200hp injectors ^^ or any "tapped" fueling box and large injectors w/quick accelerator pedal release.what are some of the main cause for that?
it's not a bad idea to. upgraded push rods wont flex or bend from the increased spring pressure and will hold the valves open without excessive stress on the push rods.should I change pushrods to or is that not needed
"Valve float" refers to the valve spring not having enough pressure to close the valve in time (usualy due to boost pressure, or cam duration/lift). This can cause the piston to hit the still open valve.when im in a hard pull and drop the throttle my truck will die unless I bump it a couple times wile it idles down is that what "valve float" does
