But the thing is, you really didn't figure out what your problem was. You put stock heads back on that were assembled correctly. Your 5.7 heads just sound like duds. THATS why your truck wouldn't run, NOT because it was 5.7 heads on a 5.3. My truck has 243s stock.
I took a look at them today, the valves was being held open on certain cylinders..
I'll look more in detail tomorrow when I drive up state to take the valves out and see what the problem was.
