from memory, the Edelbrock carb bores are 1 and 11/16 so you need to modify the the too small spacer bores and too small 1 and 7/16" intake bores to match the Edelbrock to have it work correct....

Plan B: because the Edelbrock is a bit to big for 292 cubes anyway is buy a smaller cfm carb that does have 1 and 7/16" bores to match the stock intake bores for more low rpms TQ.....

as always: "time or money"

the 600 Edelbrock will work fine on your motor, they are the simplest to tune, I'd go the spacer and intake modification route....
heck, ya want a phenolic carb heat insulator anyway (even with a different carb) for best performance
a spacer does typically help low end TQ on a stock manifold so it will offset the performance difference of a smaller carb advantage (not a big difference either way)
