Hi, I guess you ideally want a cvh specialist? I know MA Developements does cossie and evo stuff but not sure on yours...an engine is an engine after all. There is a company next to the top gear track in duns fold with a good reputation but cannot remember their name. I wonder if Burton power could give you a list of people.

If not I would try to find a race series using these engines or something like formula ford and see who does theirs.
