Yea, pretty much. You can use the cathedral heads on a larger bore motor, but you can't use the rectangular heads on the small bore motor, valves are too big... And small bore is all relative... 3.9xx inches is pretty big lol. In all honesty, if you're going to build the thing anyways, have a stroker assembly thrown into the LS2 block. My budget for the lower end is about $3k in parts and machining. And that includes a rotating assembly $2000, $700 machining and assembly, few $$$$ for coated clevite or king bearings. Something to look into. Just as an option. And then you're looking at 500+ to the wheels.

You'd be right at $3500 with the purchase of the LS2 block if you are budget conscious. Which for me... Budget conscious, is IMPOSSIBLE.
