Got the final quote and it was going to be 200+ materials. I am getting a qoute for 5&10. It looks like I might get down under 150 per set. I was thinking of just running at least a set of 5 but will go 10 if enough interest. I can probably speak for 3 right now. I am making some headers for a friends 190 with a 3.6 swap after I get mine done. I might do 2 sets.
