'82 Coupe motor questions

["Ken Keith" <auditude@neta.com>]

Hey, what's the difference, interally or otherwise, between an '82 
Coupe motor, and an '85 4ksq motor?  Are the heads solid lifter?

I'm asking because there's a Coupe like that for sale for $500 
locally, and if I can use the motor to get the 4ksq running, I could 
part out the rest.  It's an automatic.

I suppose I could actually drive the Coupe instead of ripping the 
motor out of it, but that would be too practical for me.

Thanks,

Ken
