Needs to ride right

Hi folks, I've been lurking here for years getting good advice and laughs. I'm in need of some more of the same... I'm making the leap to graft in an S-10 front clip to my 50 Bus Coupe. Steeriong box blew up so... Anyway front springs on the clip are stockers, (96' 2-w/d V6) and I'm running a 302 and C4. I read IROC springs make the difference in ride. I don't want to do all the work and have to crawl over RR tracks. Any help?
