Default Fuel Log, needle & seat

Tom,
I was planning on using a Holley 950HP carb out of the box. Will it be OK, or should I change the needle and seat to something else (obviously I don't know what I'm talking about)? My engine is a KC482 with a port matched Blue Thunder intake.

What do you use for a fuel log? I'm going to do a return line. Should it be on the end of the fuel log or use the bypass regulator you mentioned?
Thanks!

The old style fuel logs bolt onto the intake manifold. This makes the original style fuel log an excellent heater for your fuel...and yes we have had problems with fuel boil over with the original style log. 2x4 are worse in this regard as the fuel tends to sit longer in the fuel bowls before being used.

The bypassing regulator we have had great luck with is a Mallory 4309.
This regulator cured all fuel boil over, and vapor lock problems.
