What do I need?
I started disassembling the car and noticed my heads are different, The new heads are for 99-02 LS1. I know that I need brackets for the coil packs, but The coolant port on the back of the driverside head is different. So far thats all that I have seen different.
I was wondering if anything else is different? What to do about that port on the driver side head, and maybe the easiest way to get the parts I need?
