Cams How do you choose one?

Thanks Nm. And Wy. I took the heads in to get freshened they said their going to put on new seals and springs and check the valve job they had a port job from where he bought them good thing is nobody wants these heads as they want alum so the deal was for me. For this engine you are correct that’s the most I can get without changing pistons but that works for me since I still going to use the 69 exhaust manifolds which have been polished inside and exit is 2 1/2”. The one measurement I do have is the pistons are down .090 took it when I put the motor together to make sure it was square and the dish is 8cc found the paper work lol. Sorry for not passing numbers on still think I got wrong answer lol.But still interested in my cam options- voodoo 700 , Jones 256 have to call them , will look at Howard’s and mopar any one else ? And any personal ones I’m open.yes stock 340 cast intake with carter 625
