want to know if these will be fine to use with blox b's

i bought these off a friend who said he bought a head package from a machine shop and they said theyre supertech but they look like stock springs!

the inner spring is taller than stock and the retainer looks like its titanium
and the inner spring clips into the retainer but the stock spring doesnt

i installed them in my head but removed one of them because i was concerned because they have the same blue paint as a stock gsr spring

LEFT IS THE ORIGIONAL GSR SPRING

also remeber reading that the aftermarket springs have no area were the coil springs are closer together on one side but both of these have that?

UPDATE!


went to a machine shop and we measured the spring pressure

stock spring was 50lbs
and the setup i had was 75lbs of pressure he said the outside spring was stock but the inner spring and retainer are aftermarket

he said they should be fine up to 9500 rpms? does this sound right?

going with blox b's in a gsr with jdm itr pistons and arp rod bolts

any input??

 

bump for help

 

you're better off getting a new set and throw that trash in the bin.

That's what I would do. If I don't know what I got 100%, I won't use junk. Just buy some new Supertech Valve springs if that is what you want. Then you know and have piece of mind.

 

should i get the max lift checked out on the ones i have first? the machine shop told me ill be fine taking it up to 9500 rpms and with the blox b's/jdm r pistons i should only make power up to 9k- right?
