Hi all, for a reason unknown to me my supplier has changed my deal and they have cut out most of the free options.I am now searching for another supplier. However this piston is available now.Piston will be the following a flat top,1/16 rings,CD of your choice,symmetrical valve reliefs and overbore size of .030-.040-.060.Sorry guys compression ratio will have to be modified by the cc's of the cyl head.I see that will be the only way to keep the price down. Thanks for all your support,Mike
