So I figure I'll start another new post on my LS 180. Long story short, injectors are rebuilt, head was resurfaced and valve job done. Put everything back together. It started when it was cold out and the grid heater was on and engine block heater plugged in. I went to start it today it was 45 degrees out, it cranked and tried to fire. It finally did and took forever to warm up and run. When it finally did warm up it ran like a champ!! It definitely likes a warm intake when it starts. I still never found the grid heater on the intake when I had it apart. Anyways, not sure what is going on, Atleast I could get my work done and two stumps dug out. See what happens tomorrow. Any thoughts?? Also what head water temp supposed to be ? Thanks , Nik
