piston questions

At least 2 injectors of which I had sent off to be rebuilt along with the engine rebuild, stuck wide open I'd discovered and washed it out like a stuck float can. I gotta get ready and head to work, can't hunt and peck no more right now. I'd told about the stuck valves in those brand new heads much earlier in this post. But I'm wanting to toss the pistons that I have in there now because they've already taken a beating.
