spring forward

hey yall i recently installed a b303 cam in my 89 vert .cobra intake 70mm tb,2step msd,equal length shorties,cat delete x mid pipes,3.55gears ,ac smog egr delete,underdrive pulleys,comp springs ,1.6 scorpion roller rockers.and not happy with it it seems like i have no more power after maybe 4 grand?i didnt get it uned yet but still thought it would be sometrhing wlse.so i just got some 3bar gt40s ported gonna go with 24lb injectors and the anderson n41.i wanna use andersons 150lb rated spring but i guess it wont sit right on my gt40 iron heads and that i should do 110 trickflow.but i dont get it both springs are 1.47width at 1,8 height.anybody came across this and can point me in the right direction i would be very thankful.
