and is there any gain by going with aftermarket rods? I see Eagle has a 6.358" rod that weighs around 850 grams. Isn't that about what the stock rods weighed? For a stock stroke NA build, the stock rods are plenty strong. Just wondering if another $400 is worth it or not.

Right now I'm leaning towards: stock crank, stock rod, KB400, 440 Source Stealth heads.

Should have a nice long block for around $2000 to include block machine work.
