Plymouth P4 valve springs

[Wimbledon37]

i am rebuilding a Plymouth P4 engine. When i bought the car, which hade been completely dismantled, there were two engines also completley dismantled. I have two sets of valve springs which are different lengths. Can anyone tell me what length the springs should be?

   All the old springs in my 230 c.i. engine are 2” tall. I can’t say for certain if a 201 engine is the same, but they should all be the same length. They should be tested on a spring scale. Compressed to 1 3/4” with a 40-45 lbs. reading. It would be best to replace all the springs. Rick D.
