leaf spring inspection..what to look for??

like the title says. i still have my stock multi leafs and i am about to throw a serious power gauntlet at them. what do i need to look for inspection wise to make sure they will stay together at least for a couple of hits with 1000rwhp on off the transbreaks?
smith race craft assassin bars,
double adjustable shocks from strange they are custom valved like a mercer/sanstuff
solid front bushings, 7/8" offset stock rear shackles. adjustable ride height front and rear boxes they mount to.
im concerned with how the clamps are to be like? and what to look at before i order split monos for the car. pic of all in a pile basiclly
