Compression Check with Carb. Off?

I have my quadrajet off my 350 for a rebuild and want to pull all the plugs and do a compression check on the engine. Any issue with doing a compression check while the carb. is off? I didn't think so as I've alway been told to hold the carb at WOT for compression checking. Just wanted to check this would not give me inaccurate compression readings. I will need to direct the gas line supply into a bucket or something to keep the fuel pump from pumping gas out on top of the intake. Thanks Guys.
