This was developed by Gary Pavlovich, Hot Heads and a casting outfit in CA. Early Hemis and Polys (315, 331, 354 392) needed a valley pan. It was developed using a Hot Heads early Hemi cast as it was very similar to the 59-66 318A Poly, however the 318 Poly manifolds had the valley covering built into them. So, you would need a valley cover to use this and I don't know if they developed that as well. I am on the 318 Poly Yahoo group and get all the info straight from Gary P. Will have to find out. It is a dual plane (180°) and so would be good for torque.
