Boost referencing carbs

I have 525sc's on my formula 336
I had one carb rebuilt ( gasket set) due to a leak inteh flaot gasket and the mechanic replaced the "shaved " float because it had come apart somewhat. he installed a stock full size float
was the floats shaved in this application for marine? or the engine install angle???. He said he saw this on drag racing setups before to not starve the jets during acceleration.
what is the proper float
this carb has rich stalled the engine a couple times at idle now
was this a fix by the previous owner, or something dominator did
of course i have not done the obvious of checking the other engine carb
thanks

the notched floats were used in the secondarys only, when jet extensions were installed..maybe somebody just stuck one in they had laying around or all they could find at the time...and back to original question..yes jets way down from factory 525's...I have never heard much about boost referencing 4500 carbs..maybe they do or they may see the vacuum signal different than 4150 type carbs which do need to be boost referenced most of the time...
