How good are these heads?

I was thinking of using them with the following combo
AFPR
hi flow exaust
eldelbrock Hi flow intake manifold
cold air intake
and a comp 264 or 270 cam
the 264 is 212/218 just under 0.50 lift
and the 270 is 218/224 just over 0.05

How much power would this combo make?
which cam is better suited to the intake/heads?

Thanks for your comments i usually can't respond due to time difference being in australia and all so give me any ideas you have.

 

What size engine are you going to be running.....I saw in your profile a 350 so.....what do you want to have? Do you want all out performance or do you want daily driver with reasonable performance?

 

yeah its a 350. it only gets driven on weekends but needs to be reliable. I just want 350 to 400 horse power fly wheel.

 

There is a lot of people using the HOT Cam which is 218/228 duration so I would think the 218/224 would be just fine. As far as power numbers, I don't know exactly, your looking around 350fwhp.
