Because we are fabricators we know what a quality product is, and will never sell something we wouldn't run on our personal cars. Our flanges include many features that make for a far superior product, and help you get the most horsepower out of your engine.
We have matched the port sizing to the OEM head casting. This allows for a smoother transition then found on the stock intake manifolds. There is also enough material in the flange to allow you to open up the ports to match your port and polished heads, or if you need we are willing to cut you a custom flange with over sized ports for a small additional cost.
Another thing you will notice on our flanges are that the ports are slightly off center from top to bottom. The reason for this is so that when you place the flange on the studs the ports line up perfectly. We know that once you assemble the flange into the final product and are attempting to install it, you don't want to worry about having the studs perfectly centered while trying to tighten down the nuts. This allows you to simple bolt your part on and know it's lined up properly.
If you have something custom that you need or need quantities larger then what we have listed, please feel free to contact us.
