Trying to seal my one piece guides, in particular the intakes, using the quad (square) rings that were acquired from Speedway. Very difficult to install without damaging/ripping seal. Does anyone have a resolve for this difficulty?

A bit of lubricant and apply a modest pressure twisting installing them.
I don´t like them...using regular o-rings is less of a pain.

I doubt bevelling the edges would seriously reduce their effectiveness.

A lot of people just pitch those and use rtv.

Anyone try warming them in hot water?

Haven't used thise seals in 50 years. A thin film of RTV will seal them., and last longer. Remember the original split guides didn't have seals.
