Get in touch with OBR, they can advise you as they build these kits. i know you'll need a different carb to the ones usually used. im sure there isnt much difference in the build.
 
I already have a 449 walbro alky carb I really just want to know what the squish clearance should be to get a 19:1 compression ratio. I may have to contact one of the well know engine builders for info but unless I'm actually purchasing a product from them I would feel uncomfortable.
