which is more streetable-comp cam?

Well here I go again changing stuff around...got 440 .030 forged flattops .150 down in the hole with 77cc ported 906's 2.14/1.81 valves comp 925 springs with comp special grind solid 562-300 [email protected] balanced assembly, etc....m-1 intake 800dp..2'' fendwewell headers...ran extremely well in 69 dart 4.10 gear 4spd car.....now going to transplant into a 71 dart street car lightened 2 3050lbs without my lard *** [195] has narrowed 8 3/4 back braced aftermarket axles rear with 3.73 gears and a detroit locker...and a 727 auto with dynamic 9.5 convertor shift kit etc..frame tied welded custom built...ss springs...relocated to frame rails..comp adj shocks....etc..etc......Now as best a s I can figure the compression works out to a 8.7...ran great on pump gas in 69dart and pulled hard from dead stop to 7grand with no bog or any signs of slowing down...ran I'm guessing 11.90's--12.00 easily with stock wore out suspension in 69....I just rebuilt the engine[which really was no need as everything was ok] resized the ly rods installed new arp rod bolts, new rings- brgs -gaskets-pump etc...heads fresh...Its hard 2 believe it ran as good as it did with the low-comp and for the size of cam...being that I'm going to auto car with higher gears should I mill heads down to 72cc to get comp up to compensate?? I'm thinking that a 9-9.4 area would be better and still b pump gas friendly....maybe 2 much cam for combo on the street?? do have another comp cam solid xe290s-10 is a little smaller...540-558lift..290-298dur and [email protected] rockers are 1.6 stainless steel adj rollers...which makes the lift closer to 600lift..and my carb is a stigmeyer 930cfm [mod holley] street tires are 28x10...need some input from u guru's
