Used a Crosswinds brand on my Magnum. Has dual bolt holes for Magnum or LA heads. Had to drill out and tap for my AC bracket but there was a place for that. I gasket matched the ports to the intake gasket. Had to hog out a little for the bolts to line up. Been on for about 1500 miles with no issues. I bought a Professional Products intake (same) during last years Speedmaster black friday 40% off sale which should be coming up but don't remember the price. Free shipping. Good intake.
