hey im new to this site.... so if any one knows where i can find cheap valve springs for a d16 Y8 cylinder head it would be so helpful, im currently rebuilding my honda.... it had some miles 230,000 and i got the valves reseated but dont know if i should use the old springs.. i cant find specs for these springs at my school. i want to test the spring rate before i buy new ones.. anyone know where i can find the specs?
