Horsepower limit for out of the box Edelbrock RPM heads

Do you have the info on how that compares to an X head on your flow bench or an X with a little extra work in the bowls and a gasket match? I have read an Edelbrock head is close to an X head with some bowl work and a light gasket match.


Sorry but no I do not. I had 8 different small block heads sitting here as I always thought I would see how fast I could get a stock type head but I sold them all last year for 40.00
I’m glad I finally wised up. Lol
