I found a new CMB valvola header in my parts box. Won't work on my MACs, so it's for sale. Appears to be 18~20* (for mono). Older style that uses the o-ring in a goove in the header. Header is made to fit a 0.625" OD exhaust spigot. Un-cut head pipe; length 1.875", OD 0.630". $21.50 shipped in the USA. Paypal (preferred) or MO.
