Has anyone seen these Jegs 260cc LS3 Heads?
I was scrolling through JEGS and seen they have a cast LS3 260cc head for only $617 assembled! Has anyone seen any testing data on these? I'm sure the springs, retainers, and valves are probably junk but for $617 a piece that would still be a good as-cast head upgrade for some people depending the flow data and tests.

So are we looking at reproduction LS3 heads? The area where the casting numbers would be looks weird. I know that means nothing, just an observation.

You would be better off just getting the "as cast" heads from GPI. A t least you know they are TOP QUALITY GM heads with good parts in them... Just sayin...
