I have a Brand new set of Supertech 1mm oversized valves, this is INTAKE AND EXHAUST, for sale. They work for the ej20 AND the ej25 heads. I was going to have them put in but used my other set and there is no sense in having these sit around. I paid $275 for them, $245 shipped and paypal'd. I also have a set of Ferrera ej20 valves, intake and exhaust. A couple are bent... i think 2 - 4 but i will double check. Spent a lot on them, since a few are bent, $225 shipped and paypal'd.
