I’ve been thinking about this and one approach that may be worth thinking about could be for B3RE to work closely with one or two specialist suppliers that might be prepared to bundle an upgrade package as a pre paid voucher for one of Mikes kits with the sale of a cyl head / rocker combo!
Not perfect but if such a package existed the awareness and take up would begin to grow. Some digital press articles in something like Mopar Connection would be helpful as well.
Anyway just my 2 cents worth!
