80 cylinder head assembly on 81 motor?

[p00tster]

Does anyone know if a cylinder head assembly from a 1980 model will fit a 1981?

I checked the parts catalog and the part numbers are different for the cylinder head assembly between an 80 and 81, but that doesn't always mean they aren't compatible. Looking at pictures, they look identical.

It will fit. The 80 from what the manual says has a bit smaller exhaust lobe for the cam and the rocker shafts are a bit different in size. All so small it won't make any real difference. In 1980 they where trying to cut the emissions as much as they could so every bit helped.
