Ok i did a bottom end rebuild and my car is spark knocking really bad at light to moderate throttle... I rebuilt the bottom with Scat H-beams, Arias 11.6.1 pistons, ACL Race Bearing and a Cometic Head Gasket... I just had the valves adjusted and it some how got worse... idk... please help..

 

you need better gas.

93 probably isnt high enough octane

in which would cause the spark knock....
