4.0 ho valve springs

so, valve springs.. OE ones are too weak for higher lift cams, some peoples are fitting sbc springs and others use some mopar performance ones (P5249464)

sbc springs need head removal and machining i think? that i would not like to do again.

mopar ones are bit pricey, those need retainers and locks.... from summit those are $530+ shipped, a bit too much for 12 sprigns if you know what i mean...

i found some pirate4x4 bbp thread that says SBI spring 160-1378 will be fine, but i dont know where to buy those... sbi cross reference table says that sealed power vs1456 should be same, those cant be found from rockauto less than $3/each but looking info im not sure about those... as those are listed also in 4.0 parts, that means those are orginal replacements... also dont know do i still need some retainers for those or will my orginal ones fit...

hesco sells a set... needs machining...

i asked comp and crane... dont know nothing they said...
