Speedmaster intake manifold

It's probably very usable and what the heck were you expecting from a 1/2 price Chinese intake...
I got one on the stroker in my truck and it works fine....
Exactly! You obviously are not using for every ounce of horsepower or you would've bought a better intake. Gasket match and use it. I bought one for sbc a couple years ago and it looked the same, worked fine.
