I don't know much about Speedmaster heads....are they USA produced or Chinese?

When you buy an Edelbrock head, you are buying the head but also the degree of confidence in their manufacturing and the R&D that went into the head. It doesn't matter if a head makes 3 percent more power if it has porosity issues or loses a valve seat after a couple years.

See hear is the faults perpetuation of bullcrap..... start right off saying you don't know much about them and then go on to say how they're going to lose a valve in a couple of years... Solely because the fact that they're Chinese LOL... This is precisely why I bought them because there was no fact about them except for naysayers that knew nothing about them...
