Does anyone know if there is a difference between the header flanges on the pre vortec 95- and the vortec 96+ v8 and 4.3 v6 engines? I was looking at 4.3 header flanges on eBay and there are only a few and none specified for vortec heads they just say rwd, 1978+ Chevy & gmc, 3.8 and 4.3 non BOP engines.. looking at pictures of the heads they dont look very different on the exhaust side but I'm not sure if the ports are bigger or the spacing is different
any idea? later down the line i would like to weld up a different header layout so I'm trying to plan for the overall cost and where I can get parts
If they are cross compatible I can use the 4.3 specific ones. If not I can just as easily get flanges from a vortec v8 and cut off the extension to one outside port on each.
