I noticed that while none of the plugs look great, the odd bank plugs seem noticeably darker. Seems odd, maybe just me. I was going to suggest a different set, or even a different brand. I had more of a high speed miss once. Changed out all my ignition parts before the plugs. Wound up being the plugs. Had switched from Champion to NGK. Put my old Champions in and guess what? Yep. I would have never thought either. Now with that being said, I use NGK plugs yet. Champion quality seems to be in the shitter these days.

Since you didn’t degree the cam, take off the drivers side valve cover. Roll the engine over until you are TDC on over overlap (180 degrees from number 1 firing) and look at your valves.

If both valves are open the same, you are at split overlap and the cam is in straight up, whatever that is.

If the intake valve is open more than the exhaust valve, the cam is advanced from split overlap (straight up). You won’t know exactly how much, but you will know it’s advanced.

If the exhaust valve is open more than the intake valve, the cam is retarded from split overlap (straight up). You won’t know how much, but you will know its retarded.

Like I said, something is weird. I’m thinking cam timing is the first place I’d check.
