well lately ive been getting this poping thing on the pas side now this started happing after playing around in some water(i hydro locked it) frist i replaced the cap and rotar which were needed tobe done but still the poping so replaced the spark plugs when i did i noticed that all plugs were ok but the back 2 on the pas side the were oiled fouled and it looked like the plug gap was smaller i also removed my holly and did a light clean with some carb cleaner and i replaced the pvc on it

so i start it up and nothing but poping backfireing noise it worse then before i worked on my truck when i put my hand on the pas. exhast has large bust of air with the poping noise
so dose anyone have any ideas on what wrong and why would it be worse with new plugs

Check to see that the plug wires are on in the correct order.

Or u bent the valves in those 2 cylinders when it got locked up .

I think you either bent the valves, pushrods, or both when you hydrolocked it.

Pull the plugs on the passanger side and perform a compression test on each cylinder.

the large burst oif air tells me you trashed an exhaust gasket. the noise is the combustion being heard. Yes, it would get worse with new plugs, as it is probably burning better and has made the hole bigger. it also may be a cracked or similar exhaust manifold or header.
