Valvesprings help

[sundkvist]

Hi
Is this the stock valvesprings in my 1970 383? The exhaust are color yellow on them and the retaner seems a bit smal for the spring. And the intake have blue on them.

It looks like it has "rotators" on the exhaust side, which I have never seen used in a Mopar passenger car application.

They are def not "high performance" pieces.
From the factory, anytime I've seen the rotators used, the intake and exhaust springs are different, to accommodate the different installed height(shorter) that comes from the added thickness of the rotators.

Do you know if the motor has an aftermarket cam in it?
Or even a factory hp cam?

IMO, about the only cam those springs/rotators would suitable for would be the std or "2bbl" cam.

It's a 2bbl engine so it seem to be stock springs in it then. I dont think it have any bigger cam in it
