Be careful when you start to build or rebuild a motor or just do your heads. You don't want to start off by trying to save money . Manley or the other one that starts with an f . Sorry I can't remember the name. A broken valve can take an entire motor out!!! Don't start that way!!!

Elgin is good for your 259 Studebaker, 425 Buick, or 390 Caddy... For your boat, I'd stick with stainless. Ferrea and Manley being both top shelf parts... PEP being a decent budget part.

More exhaust valves are failed from incorrectly set up and regulated O.T. headers than anything else! The higher the HP and RPM the more you need better valves. We use Ferrea Super Duty valves in the good stuff with O.T. headers, you can drop back to the Special Alloy for Lightning dry type exhaust. Less HP, like hydraulic cams, we use a minimum of their 6000 series. "Get away with" and exhaust valves should be a mutually exclusive deal.  You can stuff a cam in anything, but how long will it live?   TIMINATOR
