My 292 +.060" has the same heads, cam and ignition.   I use Autolite #46s.  Never had a problem.

Excellent. I'll go with that. How does yours run? I'm curious what to expect.

It runs great.  I love that cam.  Great mid range torque.  My car has a manual transmission with O/D and a 4.11 gear.  The 465 cfm Holley carb is perfect for the street.  Idles at 800 rpm with just the right lope.  You are not going to run down any Hemi Challengers, but it has plenty of grunt.
