If I'm not mistaken the stock LS2 heads flow around 260 cfm at .600" of lift.
Patriot Ported 5.3 heads flow 296 cfm at .600" lift per there flow chart.
https://www.patriot-performance.com/...ome.php?cat=36 (list of all 5.3 heads from Patriot).
Going by there web site, they offer them in 67cc and 63cc assembled and 63cc bare (part # 2007 for the 67cc and # 2027 for the 63cc). What I'm unsure about is if those chamber sizes are for 4.00" bore or for the 3.78" bore of the 5.3L?
