318 cylinder head choices

honestly i have not looked into any cam or pistons yet. Im doing the underbody/rear axle/front suspension and disc brake swap hopefully all this month then send the car for paint. Im trying to get a little head start on the engine so im not looking for heads and paying a premimum. any suggestions would be greatly appreciated my only other rebuild was a 318 with mostly stock parts and my built 302 in my 88stang. I beleive i have heard alot of good thing about the xe268 cam? Other than that i know for sure i will be trading my mopar performace single plane for a rpm airgap or buying one.
