PSI Valve Springs & mopar performance hyd cam

the guides have been machined for the inner of a double spring, so it looks.

stay away from rusted springs...they will break sooner than later, the pitting is a sure tell wether or not to use them.imo

A mild surface dust of rust is not bad, but surface damage/pitting is.

you're missing some springs, so....just buy another set for $80-$90 of the comp springs.,,,you gotta remember the springs cycle and loose an average of 7 psi after a lil heat cycling.........the last set of mopar '847 springs I used lost 12psi, had to shim them up.

You might also want to throw a retainer and set of locks on and measure the valve spring installed height cause you never know how deep they machined them. They might have just had the minimum taken out to run springs with a 1.7" installed height or they may have taken them down more so 1.8" installed ht. springs could be run. That's another thing you need to know when you select valve springs.
