Been busy, haven't had time to get after spark plugs until tonight, just been PB blasting them for days though and did get all of the three cracked on the drivers/easy side, and pulled the easiest one in the middle, cylinder 5.
The plug looks original, it is an autolite 300, the electrode is completely worn off with some carbon deposits.
I measured the gap out of curiosity and it is .080, lol
Compression was 115 psi in cylinder 5.
Going to get wheel off and get after other side tomorrow. And try to finish.
I have some Ngk platinums and am currently gapping to .054
Would anyone recommend going to .055 or 0.056 instead.
Ignition coil is getting power. I will test wires as well tmmrw.
Odd thing... it sounded better turning over with only 4 plugs igniting at the time during compression test (had 2 plug wires removed) and fuel pump relay removed.
