74 power wagon dream truck...

Okay everything is ready to go...
The three (in my opinion) contributors to the ultimate demise of the head gasket I feel I have addressed...
New distributor with 18° of total mechanical advance and no vacuum advance... I will set initial advance at 14° and confirm 32° once it's warmed up...
Replaced fel-pro 8553's head gaskets with 1008's....
And pumped out all of 87 octane and put in 91 non-ethanol..
