Hey guys, i just bought a set of Comp Cams 1.85 ratio roller rockers, guide plates and studs off ebay for $150, just couldnt pass it up for that price. I just want to know what else i will need to install these. Do I use my stock push rods and lifters? Will my springs be too weak, is it absolutely necessary to change to a stiffer spring? Will LS6 springs work?

 

what else is done to the truck

 

internal engine is stock. just bolt ons: headers, 3in exhaust, k&n air filter.
