Hello,
That is true. I saw on the internet, a twincharged 20V setup, using the standard SC12 bottom mount...grr...all my effort (and friends!) to mount the SC14 on funny angles...oh well....
On another note, what is the spec of a group A 4AGE cylinder head? I found somebody who is selling one. I'm not sure if the bigger valves (I dont know how big) and porting are wasted for me since it is apparently a small port head. Or are the valves the bigger restriction?
Maybe I should look at some bigger exh valves for my bigport head. I heard that 3SGE valves can be used. I have not investigated.
