ITS RUNNING!!!!!!
Before cleaning the plugs I forgot I had unplug the injectors to do some vacuum tsets. That is whty it didn't start after the cleaning. I think the biggest issue was the vacuum hose into the new plenum. the o-ring with the kit was not big enough and things went down hill from there.

Thank you to all who responed it helped a lot.
If anything is to be learned from this is if you think your head gasket has gone. Inspect that plenum really closely. I looked the 1st time but did not see the hole between the RGE hole and the coolent jacket.

Thanks again and keep up the great work.

Change that oil ASAP. I recently had an UIM failure that hydrolocked the motor. I rebuilt the top-end and put a new UIM on and it ran great for about 70 miles then it spun the #1 rod bearing. That forced me into a complete rebuild. Not trying to scare you, just dont want to see that happen to you too.

I agree. Get that oil good and hot, and drain it completely. If you don't, it may cost you a bottom end (might be too late already).
