Should have just gotten a ZZP Catted Downpipe...better performance, MPG's, and a non-clogged cat.
As for the build...its up to you fish, its your car. Like Nick says and I'll say...what do you want it to do? a mean as fudge street car or a track bastard?
Heads, DIY them...or buy Selliot's...he has a set of stage 4 IR heads for sale sitting around 1500 IIRC...if I had the money for those and not invested into the L67's I got right now...I'd get em. Also...ARP everything...rod bolts, main studs, head studs, and even header bolts IMO...if your gonna do it...get it done right the first time and don't skimp.
