1.5 vs 1.6 on a 406

what do U builders think about intake & exhaust ratios?
stay w/1.5's on all 16 or mix'em up w/1.5's Int/1.6 exh. or 1.6's on 16 valves
have a 263 int/273 exh @.50 cam w/13.8:1 c/r 406sbc. TunnelRam in a flat bottom boat, got 1.6 on the heads now, but the builder didnt do a good job of ck'n the 1.60 springs vs. the underside of the rocker, alum in the filter so I'm gonna get the correct rockers for the springs, so nows the time to decide on ratios and what about useing the old push rods 8.100 on 1.5's? its a no-no
