I'm not necessarily agreeing with the cam choice offered up by Butler but for conversation compare a XE lobe with a QXI lobe.
Lobe 3317
294
242
164
.3600"
Lobe 13454
295
243
164
.3990"
Other than maybe consideration regarding spring choice is the QXI lobe less streetable compared to the XE lobe ?
"If you want to build a street motor with the most power without a sacrifice of idle and low speed qualities, then lift is the most important factor to maximize, not duration. The best suited cams are those that seek to maximize lift while only adding a minimal amount of duration."
