Keep us posted on how the fuel lines terminate to the injector tops.
On the Car Craft Anti-Tour last year I ran into some regulars that had a Jeep 4.0L head with EFI on their straight six in a gremlin and used the plastic fuel line from the pump to the fuel rail like a stock application. They said it was real easy to put the line in hot water, slide it on to the fitting, then done. At the parts store I see both 18" patch kits of the plastic line and 3+ feet long rolls of it. So it's readily available.
