To get 500hp out of a 289, you're going to have to rev the piss out of it. At the kind of rpm you'll be talking about, you'll probably want titanium for the weight savings. But I'd wait for more knowledgeable answers than mine. What's your engine combination looking like?

SS valves are what most racers run that can't afford titanium. There are different quality and composition of stainless steel that would be a desiding factor in the ones you purchase for your racing/street application. Also, most SS valves are one piece verses most stock valves being two piece (in the past they were).I have run Manley and Ferrea SS valves in all of the race motors I have built with no problems. The others, well, I would be somewhat leary about them and where they came from. But that is just my .02. Some guys on the FE board have used the EPN's sold on eBay with no problems. ------------------

If you are going to see over 7000 RPM SS valves are a MUST in any engine. Qualities vary among manufacturers, but you can't go wrong with Speed Pro, Ferra or Manley.------------------

If you need new valves, go ahead and get new SS valves the first time.Just ask again when you go to buy some for there are different quality and materials from the same manufacturers such as Manley and Ferrea. I am sure Alex will steer you in the right direction for your application without cleaning your wallet out at the same time.
