Plugs all being consistent rules out compression and likely any other mechanical cylinder issue. The valve springs probably need checked but I doubt it's the problem here as it would likely be a high rpm misfire.
A worn distributor gear will retard the timing and cause a pope and misfire. Ask me how I know...
Check the fuel pressure and timing before you waste more time.
