P4529215 valve spring pressures?

Post by GASnBRASS »

Does anyone know what the seat and open pressures are for the mopar performance spring P4529215? I'm using a MP 228 cam with .430 lift and don't need more spring pressure than stock. Trying to decide between the MP P4529215 springs or just using a melling VS2225 stock replacement spring. Going to have the valves cut and reuse the stock retainers and keepers so compatibility is key.
