I think I am going to try and call them when I get off of work if they are still open and clarify... Otherwise I think I am just going to go back with OEM valves and save myself the thousands.

As my title states I have a question about upgrading the valves on my RB25DET NEO engine. I had a timing belt mishap that decided to bend all 24 of my valves so I am needing to replace them. I brought the head to a machine shop who ordered Ferrea NEO valves (par numbers F1935P & F1933P) and upon arrival they were different than the OEM valves that were in the engine. Keep in mind I have not seen either of these valves in person yet. Supposedly the OEM valves are 6mm at the stem and then about 1cm from the top taper down into a 5mm stem. But the Ferrea valves don't taper down - they just stay 6mm the whole length of the stem - thus is requiring me to replace all my keepers, springs, etc (everything to do with the valves) resulting in a MUCH higher cost than anticipated and much higher cost than I can afford. Essentially what I am wondering is if someone has replaced their valves with Ferrea ones and kept all the other OEM components such as keepers, springs, etc. and had it work just fine. I am starting to wonder if this shop is just trying to get more money out of me.
