I assume you mean valve lift is .615 not cam lift? Is that a flat tappet or roller cam? I would recommend a retrofit hydraulic roller cam over a flat tappet cam any day. Also you need to check because many aftermarket SBC heads will allow for .600 valve lift max. IMO, you should be looking for a cam with something in the area of .540 to .550 valve lift. I'm running an Edelbrock #22015 retrofit hydraulic roller kit in my 383 and it has very good street manors around town with 210cc RHS heads but will still make around 500hp.
In my build I used a complete Scat forged rotating assembly with 5.7" I beam rods. I did not have any cam interference issues but the block does need to be clearance in some areas.
Just be sure to verify the max valve lift of your heads before buying a cam.
