I am getting ready to build my head and want to know what is the best set of valve springs, retainers, valves and seals, etc? I'll be sticking with standard or stock sizes and the stock AP1 cams. Also, I will not be doing any port or polishing as I have never seen any real gains to doing this. I just want to make the head "bullit" proof basically.

Brian Crower? Uses stainless valves that are Nitrate coated. Don't know the retainer material.

Supertech? I think they use stainless also on their valves. They use Titanium on their retainers.

Ferrea? Uses Inconel valves I believe (very strong!). Don't know what they use on their retainers.

Inline Pro? Not too sure what Inline Pro uses for their valves. I think they use Titanium retainers.

I want the best that is out there so I have no problems at all after I have it done and I can rev the engine to 9500+ rpm. I'll be going for 650-750 whp so whatever setup is the best. Anyone have good luck or know anything about any of these companies valves/seals/springs/retainer sets?

Thanks for the help.

 

supertech use's titanium. Thats what I'm using on my build.

 

+1 for supertech

 

thanks for the input.

I know Supertech uses Titanium for their retainers but do they also use that for their actual valves? That's what I'm trying to find out, the best overall full package....valves, seals, retainers and springs.

 

im running ferrea, no complaints. never ran a diff set so its hard to judge. overall im happy

 

They build them in stainless, nickel & titanium. It just depends on what you want.

With what ive listed in the first post, what would you recommend would be the best? Nickel, ti, stainless?

 

If you use Supertech stick with Inconel Exhaust valves, if you use Ferrea they have a Super Alloy line that can take the heat.

Supertech as lots of different sets of springs to choose from, I let Inline help me.

Honda Valve Seals are the only way to go

 

Thanks man, thats some good info.

 

Honda valve seals are what I used also on my head with supertech springs, seats & retainers.
