Ford has a 429ci/7.0 litre engine in its larger trucks in 1991-92 models it is Fuel Injected . Are the gaskets the same as the 460 FI engines??

 

My books don't show a 429 past 1990 in trucks. The 429 and 460 were basically the same except for cubes up to 1985 after that they started changing. Hopefully number dummy will come up here and answer your question. If not check out gasket catalogs on line and you should be able to pull up an answer.
