Question Intake manifolds

Somebody knows the "Professional Products" brand?
I was seeing photos of its products and the intake manifolds look like the Edelbrock.
It has the types RPM, AirGap and Torker, satin and polished.
In eBay selling them very very cheap.
Some comment?
Thanks

Yes, I've seen them. They certainly look great, and they are CHEAP too! I really don't know how they perform tho. I bought an Edelbrock D.Q. manifold on ebay, and the guy shipped it in a pro products box. He said he took the D.Q.'s off and put the Pro Prod. polished one on his car. I'll ask him (if I can find his email address) how he likes it, and what the performance is.
Speedway is also selling these pretty cheap too, but the prices on ebay are hard to beat.

I recently attempted to use one of those intakes on a customers vehicle, I believe it was the "power plus" line, it has "made in china" stamped on it, I bolted it on 4 times, each time with a different gasket on a set of vortec heads, the front and rear water ports on the intake was smaller than the size of the gasket, resulting in a water leak each time, finally, the customer got fed up enough and bought a edelbrock performer for vortec heads and it solved the problem right away. the ports in the other intake also were a disaster. they looked as if they had been ground out with a hand grinder. these intakes may work well on stock pattern small block heads, but they sure don`t on Vortecs, very poor quality control on them. just my experience with them.

A friend of mine installed a motor (SBC) that a customer ordered from a "performance" engine builder, the manifold on it was NO NAMER (might be what you're talking about). It was shoddy at best, and the material looked pourous. The runners looked exactly like doublevision described, if this is the manifold in question, don't get it.
