Go for the trickflows, they have 2.02 intake /1.60 exhaust valves, the afr 165 have 1.94/1.60 valves, the trick flows will flow better & you can port them... if thats your thing.
a good combo is the trickflow #1 cam, twisted wedge heads, 1.6 rockers, trick flow street intake, that is good for low 12's
950 is a good deal, summit racing sells them for 1025
