Lozza, Ive spoken to a guy that can fit the flat top piston and work out how much to machine off the head to get the compression back to normal. I want to do it so we can say okay guys if you use this piston then machine off 25 thou or whatever to make it simple so anyone anywhere can take it to their local machine shop and get it done.I will keep everyone posted as it happens, its just with CD6 happening Ive been too busy. Cheers John.
