Are Speedmaster elec fuel pumps any good ??

I bought a set of the speedmaster bare aluminum small block heads. I havent had my machinest look at em yet. He has done some SBC speedmaster heads. He said those were decent for the money. Basically Edelbrock copies, and the guides are typically junk from the get go. He replaces them with better ones before he even starts. That being said, it's a lump of aluminum. Kinda hard to screw that up. And once my machinest goes through it all, it's all good. As far as fuel pump though, thats a gamble. Lots of little pieces that have to be just right, and right from the get go.
