if your gonna do a rebuild and not rev higher than stock you don't have to change your valvetrain (valves, retainer. ect), the head could just be left alone if it is still in good shape. for the block rebuild i would get new pistons that are forged and high compression if you r going to stay n/a, then bore alittle, but not too much makes cylinder walls week. for the rods you could probably use the stock rods after recondition or get them shoppined. hone your block out put the pistons and rods in w/ the stock crank and aftermarket bearings and your good to go.

when my supra was n/a nos, i rebuilt mine w/ stock bore but aftermarket pistons and my compression was round 10.5:1. i used my stock rods and reconditioned them, aftermarket bearings, and stock crank. then i just honed my block out, the car lasted 2yrs on 75 shot w/ me spraying like crazy. i was gonna do 100 shot but went turbo and blew my motor. my supporting mods were full race port on the head, my head was also rebuilt w/ 5 angle valve job, w/ 440ccs, safc, fpr and i think that was pretty much it besides just the basic bolt-ons
