Choosing valve train
I have come to the point where I feel need to upgrade the valve train. However I am not great with these thing. I have a b18c and plan to make tops of 350hp. I see alot of people using stainless steel valves like Ferrarea(sp)and other stuff like omni and Rev. I am leaning to rev because of the coating. However, I do not know much more about choosing. I did a search, and it seemed split abit, with alot of people actually leaning towards Ferrarea(sp). I jsut want a decent alternative to the stock stuff, that will last reliably. Can I get some input.

Re: Choosing valve train (hybridrex)
Good old Boosted Hybrid claims bone stock GSR is reliable at 350 whp, so you're probably splitting hairs.
Ferrerererea (heh) has been around for ages, and is a trusted name. Pay attention to the good word, ignore the blind Brand Loyalty. Look a little closer into Rev - they use stainless of some nature, likely it is the same heat tolerant alloy common to turbo cars that Ferrererea uses.
That said, heat tolerance means very little, in my mind, since stock valves don't melt in 350 whp boosted applications. Coatings are good since they actually lower the valve temps - a plus to Rev - but I wouldn't particularly care about that on the exhaust side. Vizard did a little ******* around back in the 70's, found that a ceramic coated intake valve was I-forget-how-many degrees cooler... the cool intake charge wasn't super heated, and you netted the equivalent of two points of octane.
Now, after that over complicated nonsense I just spewed... refer to the above, that your stock valvetrain is probably just fine for your desired power level.

I would check out ef-1 as well, the valvetrain is put together very nicely. All the parts compliment eachother very well.
