Default What valves are recommended for 15 psi +

Im getting ready to build my Full LS motor ---dont need that vtech crap.
Everytime I am ready to build it I find a great deal on some kinda part.....now I found some valvetrain.
I plan on doing some crazy Jinxproof stock sleeved motor. Gonna be boosting 15 or so on pump gas.

Anyways.....what valves would you guys say that I use? I would like to stay away from oversizing since I will be doing the port/polish work myself and dont have the facilities to machine the head at all. OR, should I spend the money and get oversize, how much .5mm, 1.0mm?? On which side. From what people say, keep the intake stock and go big on the exhaust.

What should I do?

My question to a T.

Do you guys think Ferrea is required for twisting the motor to 8500 on occasion? More like 8000 daily and 8500 at the track.

Stoopid. I know you have had a lot of good luck with LS motors. You think I should stay with stock? The cams Im gonna be running are really wild....way more aggressive than any turbo cam out there....totally custom---some may know what Im going with...lets keep that a secret

I've talked to a few people on here and some like Ferrea and some like Skunk2, but I have also run into people, particularly 2K_TEG, who at the time was planning on using Manley valvetrain components.

I contacted them and they sent a free catalog and it's has a lot of information. They cover all cars, both domestic and imports, except for Mitsubishi

But in actuality, I plan on running all Skunk2 products in the valvetrain except the cam. I'm still unsure on who I should go with about the cam. Any suggestions?

So for you guys checking out different valvetrain companies, try out Manley and see what they can offer.
