If you buy the QFT plate kit for the side hung bowls, it comes with a clearanced float.

And I agree with the gasket getting squished into the channels could be an issue if higher fuel flow is req’d, and that using the steel plate with the thin gasket is preferred.

I’d probably shorten the Jets a little if it would give me enough to add that steel plate & gasket back on the carb.

Although, I’m pretty sure that if you buy a new generic 4160 carb(3310/1850, etc), the steel plate and thin gasket are no longer installed in those carbs.
