Valve choice

Post  Super Snake Steve on October 25th 2013, 12:00 pm

After surfing the internet I always end up back here to get a real answer so thanks for all the advice.
I have a 429 scj bored .30 over forged pistons a bit more cam than stock 563 int 583 exh duration246/256
Solid flat tappet cam roller rockers bronze guides and exh ports polished I built this motor in 85 it's has 15k so I pulled the heads to have valve job and update them so I advice on should I just get valve job and that's it do I need harden exh seat and stainless valves if that's the best way to go I'll spend the money and have that done if it last longer and performs better if not then why spend extra money if it's not of benefit

One more thing do have to have harden seats to run unleaded gas weather you have OEM valves or stainless valves?

Yes you really need the hardened seats, but stock valves will suffice on a street engine and mild rpm. But I would buy them new.

Just check prices you may can find stainless for just a small amount more.
