6.4camshaft swap 5.7 Rt

Please I need help
I swap my 5.7camshaft to 6.4 only
I didn't change any others
I read about I have to change valves springs and push rods and retainers
Cost of all of that including labor charge and tuning more then 1000 $
So I'm totally confused I go and change them all or I go for 274 comcamp as I know it's not require any of other changes and I will get the nice loopy idle with the same or more hp depends on mods and tuning
Really I need help Coz both options are smiler to me
Also please consider I live in Middle East it's not easy to get the parts and cheap labor
The mods in my 2010 challenger RT
-k&n cai
-Diablo trinity t 1000
-flow master catback
-with jba short tube with catless pipe (not installed yet )

You have to as lest do what the recommendation are as per the Cam MFG to get the performance out of the cam.... If you have not done that...Yes you can hurt something in the valvetrain....

So you think I should stick with the 6.4 cam and change the valves springs and push rods and retainers much better or I should go for 274 camcomp as I know it's not require other changes on head
I know if I keep the car like that it will heart the engine that's why I'm not driving the car now that much
Also can I fix the 6.1 valves springs , retriners and posh rods or I must have the after market one

I'm a little confused.... Correct me if im missing something.....
You have a 5.7 in your 2010.....
And you installed a 6.4 VVT (Varible Valve Timing) camshaft in your 2010 5.7
And the problem is What?????
And What / Whos cam did you install?

I'm Going to Guess your trying to build a Scat Pack out of your 5.7....?

Lol
It's little confusing I know
My car 5.7 RT 2010!challenger
I installed the 6.4 cam only no other changes has been done in my head cylinder
So I will have to pay around 1300 $ for the new head parts ,labor tuning
I read about 274 camcomp that can be fix it with no requirement of changes head cylinder internal and will cost me around 1500$ so
I have to option I need some one who had experience to guide me
I go with head parts on my 6.4 camshaft
Or I change the cam to 274 camcomp
I hope you get it
Sorry for my bad English

Arrington Performance are get guys.... They have that Hemi powered Wagon putting the hurt on folks...
I Am not much help. I have not done one of the conversions..
But would say... Using Arrington Performance Or CompCams... you cant go too wrong...

Just my 2 cents
