911 heads coming off sunday! help!!

What are some good cam specs for this setup
ported heads 202 valves 1.6RR all bolt ons
was thinking 224/232/550 lift(w/ 1.6rr) on a 114 lsa?? suggestions? i plan on spraying a 150 - 125 shot but only as a back up so i want a good (on the motor) cam but something that will apreciate a lil spray.
i am going to have a Custom cam made need some ideas.

put cam in at TDC?

Thanks for any suggestions


o and what about brakes after the cam will i need to upgrade them because of the vacum loss? if i do need to upgrade what do u guys suggest i do?

If you're looking for a cam recommendation for your heads, you're going to need to look at more than just if they're ported and what the valve sizes are. Things like intake and exhaust runner volumes, flow numbers, and where the flow peaks are all going to come into play.
