hello

is it possible to use 800cc heads with 1000cc barrels?

I bought my R80 G/S bike with 1000cc barrels but I’m not fully sure with the heads are the original or if they were changed.

It still has the 32mmm carbs... the exhaust head pipes look like the original

Ps: what should be the correct jetting with 32mm carbs with 1000cc barrels?
 
Take them off to measure,
They do have reference numbers cast on to the lowest fin but I doubt you will be able to see or read them.
I wouldn’t know if the information gleaned would be of any use,.:confused:
The 800 heads have a recess machined to accept the raised lip of the barrel,
Also you can measure the valves to confirm
 
150, 2.68, 2nd , 1/2" down works fine for me, with a bit more flow n the air box and a Staintune G/S type exhaust system.
Squish is usually acceptable if the correct low comp pistons have been used, but nice to check and when you have it apart to check as Mikey has said you might as well optimize it, good bang for the buck.
