16 bolt valve cover gs1100e head on oppose to 20 bolt

[liberman.kevin]

are theyre a difference in hp between a 80-81 head in oppose to 82-83 gs1100e head. I ask cause i have a 81 gs1100e with the stock head and have a 82-83 complete head with cams ,and valve cover, on my bench , i was wondering if it will bolt right into my 81 and if its worth the effort to get hp out of it, if so about how much more hp will i see thanks

Only difference they tend not to leak as much and the cams profile.

good practice but no real gains.
now an 1150 head...that would be worth while but half the studs need changed.

Get the head ported that will make a nice difference, bump the intakes to 28mm 1150 valves

Also, they are 20 & 24 bolt covers, not 16 & 20. Ray.
