What head should I use with a Polossi and 60mm crank?

I was thinking about using this one:

But, is the Malossi combustion chamber going to be shaped incorrectly? With a packing plate, which should I use? Thank you!

Hi dude

 

what was the question ?

Do you want to know if it works with the o-ring ?

 

And by the way - do you use a rotary valve or a reed valve ?

 

cheers
