![]() Does anyone know if the '87-'93 5.0 E7 heads work on a regular '83 5.0 motor? I'm worried about the piston to valve clearances. Do the pistons need to be notched?

![]() People swap them onto 86 GT's all they time and those are flat top pistons, so I would think you would be okay, bolt one on and see, that's the only real way to know......ya know.

![]() I asked a friend about my question and he told me the '83 5.0 L V8 (Non H.O.) pistons have no valve reliefs and the valve will hit the pistons. Anyone know if this is true? I want to install '87-'95 E7TE heads on a '83 5.0 L 302 V8 (Non H.O.).

![]() They will work, just be sure to check clearances. Especially with a cam .500 lift or larger.

![]() This probably won't help much at all, but I have a .512 lift cam, 1.6 rockers, and E7 heads which were shaved .03. The intake valve was .01 closer than it needed to be at .09.

![]() Thanks, I'm going to pick-up a pair of E7TE heads this weekend for $75. They're going on an '83 5.0 L 302 (Non H.O.), but I'm not changing the camshaft until I'm exactly sure what I'm going to use, Carb or Fuel injection. I might even use a roller '85-'95 302 shortblock. The heads are going on a full sized '83 Ford Bronco 4x4.
