Been helping a 90 year friend with a 35 chevy truck. I am not the first guy in this engine, many years ago he had head rebuild and I would say they used wrong valve springs way to heavy. Can't depress them with a screw driver way to tight. I would like to put it back to stock need replacement springs new or used and some push rods as well. anyone that could help point me in the right direction would be much appreciated.
