Spring blockers don't help that much at your power level...even though they probably wouldn't HURT anything.
I'd suggest driving around the water box, removing the headlight...setting the tire pressure correctly around 25-28psi.
I did 13.6x at 101.whatever with a 3.4"/1.84 rockers/exhaust/DHP and a 1.8~ 60 foot. Had other babbles like poly mounts, suspension work, shift kit, intake, ported GenIII...yadayada if I remember right. It's doable...just don't expect miracles the first time out. Ever.
