440 source stroker kits

I've built 3 505s, a 496, and 2 451s with 440Source product. Source's pistons used to be source numbered by Source but made by KB. I think the Icon line evolved in part from the relationship with Source and now they just say Icon. They are a good value. The cranks are hit or miss, but always "within factory specs". I have not had any that didn't have some taper. Some very little, some at the high end of the allowable - and that can be different journals on the same crank. They are also not polished to as smooth a surface as some others. Indexing and stroke have never been any better or worse than anything else available. I have never had to turn one to fix any issues but know others that have. It's up to your builder and his understanding of the intended use. The rods are good pieces but the last set I had still shipped with oil on the threads - not the right ARP lube. When the right lube and ARP torque values are used, the big ends distort. The pin ends are never the right size and emery cloth is not the way to properly address that. I always add the cost for resizing both ends in my estimates when using Source rods. I do not trust their balancing so I pay my shop to do it to my satisfaction. Stealth heads are good value but the E-Street RPMs would probably be a better choice at this point. I replace the springs, seals, retainers and locks on any Stealths I run, and they get a good valve job and deburring of the chambers, spark plug boss in the chamber, and rocker stands. That valve job is the same as any aftermarket head. The hardware on the Edelbrocks is better and I routinely re-use thier stuff with my own spec springs.
