I'm considering having some high quality custom inlet valves produced for the M20/21...These valves are not really for use in standard engines but are better suited to the few people that visit the forum and are involved in building M20/21 sprinters, sand racers etc. (you know who you are!!)..:laughing: ....Some engine modifications will be required to fit one of these.
Post here if you are interested not forgetting to enter your details in the e mail 'option' box or contact me directly off forum if you prefer....Ian
