Well, Marlin is the second person to comment on this and it got me thinking. Wilkinson saw the car running and essentially said "Closed chambered heads would add about 100hp!". That would be great if it pans out and I will take almost any fraction of that. I recently found a set of original and unrestored D0AE closed chamber heads and will try to get them setup similarly to the open chamber heads currently on the car. That way I can safely swap them in and hopefully enjoy the performance improvements described above.
