77-79 GS750 head on a 78-80 GS1000

Hi!

Anyone who knows if a 77-79 GS750 head
will fit on a 78-80 GS1000 engine?

As the studs pattern looking to be the
same and the camchain length should be the
same also as it have the same partnumber
I was thinking that the 750 head
could fit the 1000 even if the 1000 do not have
the idler gear for the camchain but not sure.

I know the 750 maybe have some smaller
valves but the compression chamber maybe are
also a little smaller too and thereby rising it compression
a little.

It is in the first place intended as a temporary
solution while redoing the 1000 head.


Anyone who knows or have tried this?

From a friend.

I ran one for many, many years. I had custom-made intake valves that were 30mm? (the stock 1000 size IIRC)
And used 29mm smoothbores with .355/.355 cam shafts. It ran like a scalded dog.
