They will be just fine with those heads, as you will have trouble with sealing them up before exhaust back pressure is ever an issue.

I'm running the .68's on twin 66's with a 403 and it's way more capeable of what myself or the car can handle. 7 psi Spool up is fantastic and no dropoff that I can feel up to 6,200 rpm.
