Personally I think your heads are decent heads. I also think your existing cam for what you want is better than what comp is telling you to buy, but then they wouldn't sell a cam. Comp cams are well tested on SB Chevy and then they assume it will do the same thing in a SB Ford. The numbers they never tell you is what is going on in the ramp portion (opening and closing), of the lobes, which is the majority of the time that the valve is open. You can change the ramps on lobes and have two cams with the exact same duration, lift, and LSA, with totally different performance.

Contact Blykins and have him set you up with a cam. I think you would be very pleased.
