Mopar Small Block Manifolds Early 1980s ? on 2040-parts.com

Here are what I believe are a set of late 1970s or 80s exhaust manifold set for the small block Mopar 318 engine. The ports are 318 size. This set has a part # of 4041486 right side and 2538478 for left side. Not sure if they are a matched set year wise. These are for a smog engine of the 1980s era. Can be used on an earlier engine if the smog tube is removed and plugged up on the right side. The heat damper works just fine,not stuck. This set looks like truck manifolds due to the fact that the exhaust dumps are in the middle position. Selling as not working due to the heavy port rust. This set needs resurfacing in order to get a leak proof seal between the head and port surface. Cost of resurfacing would be in the range of $40.00 ,[my area] at most auto machine shops. Sold AS IS needing work described and not working as they are now. These have some weight. 45.00 shipping to lower 48
