I’m interested in changing the stock power valve in my 1956 to a 4.0hg. Does anyone know where this power valve can be obtained?

I've looked and the power valves they sell look similar, but different t if that makes any sense... The ones in the original Holley 4000 don't have the exposed spring and I think they are a little shorter. I bought a complete rebuild kit and the hg isn't stamped on it. I believe the originals are 6.0 he which is a bit too high of a vacuum pull for these motors.
 
Good luck in your search, are you having a lean burn issue? Problem may not be the power valve...
