All the stock LS1 heads (806, 853, 241) can make equal power with the same port and valve modifications. Most agree that 241s flow a tiny bit better in 100% stock format though, due to the casting proceedure.

853 use center bolt valve covers and an ignition coil rail that bolts all the coils to the valve cover as a single unit.
241 are the same as 853s but were produced using a slightly better casting method that results in ever-so-slightly better port walls than the previous heads.
They all have the same potential.
