'89 360 LA valve spring/cam confusion

The motor came out of a 1989 350 Dodge Service truck, had Thermoquad on it.Yes 308 heads & stock compression. It will be going into a 1967 Barracuda Fastback with a 904 transmission going through a 7.25 rear axle with 2.94 gear ration. Plan is for it to be a retirement project that I can drive to car shows & the occasional road trip. Will probably forego the 2.02 valves as they aren't really needed for what I have planned. Will just go with a basic 3 angle valve job & a clean up. My biggest question was how much lift can I run with the stock springs ( they will be new), since so far I haven't been able to find any aftermarket springs that are recommended for a specific cam?
