All motor questions

[98LsCoupe]

I've got a 98 ex, "jdm" headlights, red/clear tails, greddy evo2 exhaust,4-1 header(off brand, not bad), it got an LS motor, block's been honed and had the crank done, ctr pistons on gsr rods, head has been redone and milled a lot to bump the compression and got all new seals, polished with no port job, 9 angle valve job. The whole thing got new seals, bearings, molly rings, cams(aftermarket,cant remember what kind, got them from a friend), str gears, aftermarket crank pully, b16 tranny w/4 puck clutch, i'm pushing prolly 12:1- 12.5:1 compression. Rollin on some bronze hx rims w/polished lip right now. 99 si seats, type r shift boot(black w/red stitch) with a no name short shifter. Thats about it. I know i want to find an aftermarket intake manifold and prolly a better header but this is my first all motor set up and i'm looking for some suggestions as to what i can do without going too crazy on it.
Thanks, A
