Re: Which valve springs for mild hydraulic roller ?
For such a mild cam I would get a double spring with a cup/locator and matching retainers/locks. No need for fancy stuff. What lifters and rocker arms are you going to use? That also comes into play when choosing what pressure you want(some lifters and stampen steel rocker arms dont like to much pressure if you want them to live).
Pull a spring and check the installed height you cant trust that it as advertised.
Since you bought your rotating assembly from one of the best you know where to go for springs. Vince recomendation 130-140 seat and 350-380 open sounds like a good advise.
Is there room to shim current springs to gain some pressure? The heads with the springs you have can handle up to .700” lift if Im looking at correct part nr. Maybe shim what you have?
