So I hage decided I wanna go with del west or xcledyne valves but can I run stock spring and retainers? Havent read any input on what people do on the springs and retainers
you should use retainers made by valve maker, as their retainer cut may differ somewhat from the OEM. honestly use get OEM valves, new keepers, get the seats done from someone and call it a day. PRO1 racing in tempe AZ does all of my seats for me, $80 per seat, I drop off a destroyed head and pick up a better than new one. Race tech also has head services now as another good option.

If a company isn't using MOLSTAR90 seat and guide material, theyre doing it wrong.

I paid 60 euro per valve seat. (berillym) that's inclusive fitting and cutting. I don't know how the prices are in the US. Stock valves are fine.

Oem is always a safe bet. DelWest titanium valves are the best you can get but I don't know what your price range is or your usage. Stay away from any kind of aftermarket Stainless Steel valves, the added spring pressure and harder material pounds the camshaft to death and the valve is heavier so it also makes the bike rev slower and not as high. If you are going to be replacing the valves at all you will need to at least have the valve seats re-cut otherwise those new valves that you spend all the money on are not going to last very long. If you want the economical package that will last and perform reasonably well, just put in oem valves but make sure you have the seats cut otherwise you are wasting your time. If you want something that will be just about bulletproof but will not have the downsides of stainless valves, send your head to Millennium Technologies with your new oem valves and have them make new softer valve seats matched to your specific valves.
Del West.....I would use them over PC's.

DelWest does make the valves for Pro Circuit, but are to made to PC's specs and are usually flat face. They are not the same as what you would get from DelWest, so you are not paying more money just for a different logo on them.
