I think it is unlikely that you changed the engine timing while replacing spark plugs..I think it would be more likely that the spark plug wires were replaced and crossed up somehow if pulling more than one wire at a time. double check firing order as mentioned and correct any wire that was crossed. The only other thing that I experienced while replacing plugs that caused poor performance was putting too much di electic greese on the spark plug wire cap which caused misfiring of the plug.

Have you pulled the cap since you replaced it, and looked at the rotor? I've seen the wrong rotor sold with the HEI cap. Make sure it looks like the old one. I remember fiddling with my rotor to get it on correctly, back when I was running the OEM 454.

2004 AllegroBay 34XB I think, I just got it from my parents.

Lifters lost hydraulic pressure and then 4 push rods were dropped. Gotta love it.

I don't think there is enough room to drop push rods with flat lifters. They would fall out all of the time.

Besides the clacking from the ones that didn't fall out would have sent you there before changing plugs.

Probably rusted valve stems made the valves stick open, causing a big enough gap for the push rods to drop.

Over rev or broken valve springs will also throw push rods.

Check to make sure any vacuum hoses are correctly connected and not dangling in the wind.
