^Very good advice.

If it were me I'd let it buck if the valve springs didn't have a ton of miles on them. If they did, I'd reaplace them with something cheap but will get the job done. No need to go crazy for your goals.

I rocked the dks regrind 272s on stock valve springs for a while making 450ish + on DB's dyno for what its worth without any problems.
