My 1978 Pontiac Bonneville Brougham has had a burned exhaust valve since 1981 apparently. Is this a common problem on the 301 engines and if so what is the best valve replacements to prevent this from happening in the future?

Best discussed with your machine shop, what they have to offer and the cost difference, if any.

I agree with Justa.

You can also reach out to TTA Performance. They specialize in building performance turbo 301s. They will definitely have an opinion too.
