My 1978 F100 has developed an exhaust leak and I need to buy new gaskets. Does anyone know what the port size and shape is on a bone stock 78 302 head because there are several port shapes and sizes on the Summit and I am unsure which ones to get. Also, if anybody can recommend a good header gasket would be great. Any help would be appreciated.
I bought the truck with the headers that are on it and have never had them off so I don't know the shape of the ports. Would I need the rectangle or the oval Percy's Gaskets?
I also forgot to ask if anybody thought the Stage 8 locking header bolts were a good idea. I would like to try them out but would just like a few opinions.
