Looking into buying a used motor 4.75L stroker MMR 1000S shortblock 9.5:1 Compression NEW Cobra iron block Manley Pistons fly cut for valves .20 over 9.5:1 compression ARP main & head studs MMR Side bolts ARP 2000 rod bolts Clevite main & rod bearings Total Seal file fit rings Felpro head gaskets Cobra oil pan
Motor has about 1000 miles, and am wondering if this normal wear on the spark plugs? I'm waiting for the exact compression numbers but dude said its at 155-160.
Thanks cafords

When you smell it you can tell if there's gas mixed with it. Smell it and see what it is and there's a lot that can work with it. But from the pictures it seems ok.

Pictures look okay. Reading spark plugs is for old men what reading tea leaves is for old women. Today we have cheap wide band O2 sensors that can tell your precisely if you're running rich or lean.
