webb cams sells valves for the raptor. $50 bucks a pop (OUCH) thats $250 for all 5. They are stainless I believe.

They have the stock size and 1mm over size. Hope that helped you.

Trinity will sell the fierra valves for I think $70 !! They are 2mm larger. Its hard to get them, always on back order. Web cams does sell the 1mm larger valves that are actually black diamond valves. Hope this helps.

 

Thanks alot. Are people going with just the center intake valve at 31mm or all 3 or all 5? I thought that going larger on the center one was all that was needed.

 

I have seen allot of people going bigger on all three intake valves, not sure if everyone is using the 31 mm or 32 mm valves, sure most don't want to say ! The exhaust are already 32 mm, but some are going bigger there too. It all depends on how much money you want to spend, and how fast you want to go I guess.
