Valve spring compressor...
I tried them all but the best is the Comp Cam tool. Mounts to the rocker shaft bosses and has zero issue compressing heavy springs. I bent 2 C clamp presses and the two armed puller worked like a bag of gravel. The Comp Cam one works with the heads installed so you can pop out your break in springs easier. It is expensive for such a simple design...the only bad part.
