Heat riser direction placement question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi, I have a 71' Cheyenne with a 350 SB that I am installing a stock heat riser on. Can anyone tell me if the couterweight and spring assembly on the heat riser is supposed to be on the front side of the manifold or the back when you install? You can bolt it up both ways, but I'm not sure which is right, and I can't find a picture. It's pretty easy to tell top and bottom, but front and back is confusing. Can anyone help me? Thanks
