Default which injector?

I'm trying to decide if it will benefit me to run 42lb injectors, or if I should just stay with the stockers. It's on a stock LS1 shortblock with 799 heads milled .010 and .040 head gaskets. LS6 intake, ported TB, longtubes, UDP, MS3.

if you stay naturally aspirated (no boost) get the 36# injectors


if you plan or are going boosted, get the 42# injectors.

All of these ratings I'm mentioning are at the standard 3 bar 43.5psi

I'm not really looking to buy any new injectors. I was just curious as to if the 42# would be too much. I have a set laying around is why I ask.

Would red top SVO 30lb injectors (F1SE-E5A) be better to run than my 42lb?
