CARB SPACERS

i KNOW this topic has been hashed,hashed and RE-HASHED but i was thinking of something today while i was in the garage.
i have a 340,hyd cam,11:1 comp.,x-heads,S/P M-1 and a 750 dp with a PROFORM body...i also run a 2" 4-hole NON TAPPERED spacer and was thinking,could that be causing my missing/leaning on top end??
too much of a spacer??
i just put on a 1" 4-hole NON TAPPERED spacer,will this help??
