Cam and Valve Springs for my 360 build

[72DMag]

Hi we are continuing to build the 360 magnum. We are running the slightly higher compression icon pistons and we now purchased a set of R/t magnum heads and an m1 mopar single plane intake.

Wanted to ask about the valve springs on the cylinder heads. We are not sure what they are and what kind of camshaft we can use with them? Previous owner said he bought them like this. The retainers appear to be the 2.2L ones. Thanks!!

Also should have added that we plan or hope to use the stock magnum rockers.

pull one off and check the pressures
guides cut for viton seals if not do it
check the spring height the how much pressure at that spring ht
then measure say .500 down
you can calculate everything from there

HR cam!
spring seats- how are the springs located?
