if its turning the motor over but not starting i would start with the fuel just pull the number one plug out and put the end on the threads of the sprk plug hole and have someone start the truck for a second or two and can tell if your getn spark and fuel

See if you can spray starter fluid down the open throttle body while cranking (not the MAF), if it fires up but dies that will eliminate the fuel vs spark issue.

There is a ground on the back of the motor, you shouldn't have to disconnect it to r&r the heads, but if you did that could be your crank no start issue. Like everyone else said i would def. check fuel pressure, spark tester is always a good cheap tool to have.
