Its the 6.2 L head, casting number is 823, theyre square port and flow better, you have to change intakes, and sometimes ptv can be an issue.

The difference between winning and losing, is having a 2nd stage.
so i am thinking of getting a 799 head and swapping the comp springs i have onto them. i heard that ls7 lifters and pushrods are a cheap good upgrade. looking into a cam in the 230ish range and with good lift. and a nnbs intake swap with 90 mm throttle body. what do you guys got to add or say about this setup?? also what year and motor do i want a nnbs intake from?? looking a rock auto and need a year and truck and engine to know which one to get. Thanks
2007 and up I believe.

Ls7lifters yes pushrods no. Nnbs intake from a 5.3/4.8.... You can get 799/243 heads off the same truck as the intake.

ok good to fnd out now!! lol and when swapping to a nnbs intake do all the fuel rails and vacum lines i have now swap over? or is there more to this swp then just buying a intake??
also when doing all of this i need new gasket and head bolts, what are good brands that you guys use?? and what pushrods are a good upgrade for 220 to 230ish duration and 575 to 600 lift cam? and will the comp springs i got for the smaller cam i got now work on a bigger one??? thanks guys
