Delco connector
If you break your oil pressure sensor clip and plug there’s hope! EFIconnection has you covered. This is so cool I’m so happy they carry this and many other connectors. These are legit and factory quality.
Very happy and satisfied customer

ARP all the way
These are an excellent choice for LS head bolts. Just know they are ARP2000 bolts not like the 4317 kit which is regular 8720 chromoly . These are super strong

Comp cams only way to go
Excellent quality valve spring kit. Tool steel is now very expensive and retainers are not being made. Grab you kit while you can. This is a popular kit .660 or the .675 version. Other brands quality and craftsmanship are not there but you definitely get what you pay for. I pay for comp cams and get high revving valve train reliability and piece of mind with dual springs
