I have a 4.6 short block w/forged rods/pistons (one bad piston)I'm leaning toward sleeving the aluminum block. If the "shadows" don't come out of the bore at .020 over, I'll need a 3V block. I have Pro Dyno and L&M testing the market to see what they can find. Still not sure whether I'll have the machining work done locally or by L&M. We'll see how the bore looks at .020 over before I need to make a decision.
Ouch that head will give me nightmares....In these uncertain times, it is equally important to rejoice and cry. So here are a couple of pictures so you can do both.

Pistons are in the hands of my engine builder now for assemble and balancing. Maybe I'll be ready to roll when the world is "open" again.
