351 Cleveland 2 Barrel Heads Or 400M Heads I Need

[xJoshx]

Hey i have a 1976 Ford F-150 4 x 4 with a 31 spline Heavy half rear end with 35" all terrain tires and i put a 351 cleveland in it. I havent come across a problem of finding parts uptill now.

I'm looking for 351 Cleveland 2 barrel heads or 400M (michigan) heads, I asked everyone i knew and they all said the same thing "good luck" so they're apparantly hard to find i guess. Anyone know of where i could pick up some heads?

If you must know the engine was tuned way back and its a compression issue which i need the two barrel and NOT 4 barrel.
