Have bought a spare head as my k1 is smoking and as it has been rebored suspect worn valve guides. The place I bought the head from does not know which model it came from. I suspect it may be from a k7 (Has studs on exhaust ports). So the question is - Can I put a K7 head on a K1 barrel? Any advice will be appreciated.

philward:
I suspect not as I'm sure the valve/angles are different - experts will be along shortly to advise!

Trigger:
Different head all together. You need a match head or why not just replace the valve guides  ;) And has it been rebored to the correct spec.

redtractor:
Thanks for the replies. I was hoping to have a head refurbished so I could do a swap. The barrels have been bored out to 836 to Mark Paris spec so should be ok. When you say the heads are completely different,(I'm not being argumentative) but in what way?

I'm a 500 guy...   8)

K0-K6 and F1 were the same
K7 and F2 different

Different combustion chamber shape / compression ratio
Different size valves

I will let the F2 guys chime in with any oil-way and head/barrel differences.
