Im looking for a good valve train set for my 383 stroker. Single turbo with low boost. Going for 600hp. Ive heard of valves filled with something to keep them cool? I have a great set lt1 alum heads. not looking into getting bigger valve sizes. Just want good valves. Titanium maybe?Any websites that help teach me which type of valves would b better. im going to port a little bit out of my heads also.

Also, does anyone kno what rocker arm ratio should b used with boost?1.5 or 1.6?maybe considered a power adder section question but if you can help i would appreciate it.

Best case would b if i could find a good valve train kit. springs/rockers/and valves. I really want knowledge on the subject but cant seem to find very much.

The cam im going to run should be around 230-236ish int/exh with a 114 LS only a .5 duration

 

Nobody uses sodium valves any more. Stainless valves are the most common high performance valves. Extreme high end valves are titanium and are close to $100 each. 16 valves in a V8

Rocker ratio doesn't care if you use a turbo or not. Rocker ratio is a poor man's cam swap. Buy a camshaft designed for a turbo and use the recommended rocker ratio for the cam which will probably be 1.5. Turbos need different valve timing because they force the air into the cylinders instead of having it sucked in by the piston. That's why they have different cam grinds.

Valve springs will depend on the camshaft but anything with more than factory lift will need the heads set up properly for the springs. There's a lot of geometry and valve train tolerances required to properly set everything up.

 

Ya i know there is a whole lot of stuff to have in mind when it comes to this stuff. Is there a place you can look up a kit online? or any good performance places i can call? does crane cam have turbo kits with the cams and valves etc?
