What upgrades to the heads do you need to get the best gain from the H.O. cams? I have seen on other forums where people said you need to upgrade your intake manifold with the H.O. cams.

When they say about upgrading of the manifold they are talking about the h/o manifold. Which are really hard to find since they are no longer available for purchase new. Im sure you will see a gain but dont expect to much from one. Im waiting to hear for some results from the 2008 4.7 manifold myself.

Ported heads. I thought about doing this but that is too much money for me to spend on them. IMO, I just dont see how having ported heads will suddenly wake up the h/o cams if you ask me. Either the power is there or not.

ya i plan to port my heads , and switch out my tuning with sct ....if this doesnt make those h/o cams wake up , im defantely going to switch to the 212x because im hearing those are better for highly modded 4.7's......but i agree with h/o statements made earlier as well....i didnt see much gain after install.....but i will give them a chance

Just curious, do the 4.7's have a 'lope' to them with the aftermarket cams? I know mod motors dont lope too much, unless serious cams are in there. At least from my experience with the 2v 'stangs, they dont sound as aggressive after a cam swap as the pushrods do.
Keep the info coming, I love learning, although it is a bit discouraging. Thats a whole lotta work just to = a stock hemi. Hell, I would almost rather just drop the big dime on a srt (6.1L) swap, unless the eaton/whipple projects come through with LOTS of success. Then that would be badass......

im not sure on that one ....that would be a good one to ask airram for sure....i think he said with 206's you need ported heads , sct (to take real advantage of those cams) , headers , and ya the 70 mm.... but im not to sure
