IMO your combo may be common in the last few years since the TF270 heads came out. Dwayne is familiar with it. So, I feel you made a good choice. Converter, gear, weight are variables other than engine. And user tolerance for valve springs is another.
Tell us your combo and the cam lobes and/or specs.
