165 Afr's on a 351?

I am in the middle of getting parts to put together my 351. I have come across a set of 165's that have upgraded springs with port work.(Cheap) I have not bought a cam yet so thats still up in the air. As for the rest of the drivetrain I have a T-5 with the factory rear with a true trac and 3.55 gears installed. I would like to get around 350hp, do you think these heads will do it? The car is mostly street driven with mabye two trips a year to autocross events. Please let me know what you think and if you have an opion on a cam also I would apreciate it.

Thanks
Nathan

I always thought the Canfields would put the headers to hi into the shock towers?
