OK, all you 850 experts...

Will an '82 head fit on an '81 engine?

I know they changed the cam cover from 16 to 19 bolts some time during the 82 model run, but other than that, are there any other problems I might expect?

I have a chance to get a head for my son's 850 this weekend and just wanted to be aware of any other problems that might show up. If this is a later '82 head with the 19-bolt cover, I will just be sure to get the cam cover, too. 8-[

is the 850 the engine has the two tach options in the same year? Don't some have the tach in the cover and some on the cylinder block? I am not sure, can someone help me with this one? I thought I read it somewhere on here.

Good point to check. I just looked at my wife's '82 850L and the tach drive is the same as my son's '81 850, and I know that hers has the later, 19-bolt cover.

Get it.
If it won't fit, someone else on here needs it.

It will fit and work just fine. Get it.

The only difference is the one you noted -- most '82 850 heads use the 19 bolt valve cover. The tach drive, intakes, cams, etc. are all same-same.
