F-16C block 30-early-what intake for a GE engine?

I have an excellent 1/72 Revell F-16C kit. I has GE engine nozzles and big mouth intake. My subject is an early F-16C block and according to the F16.net site both P&W and GE engines of the early block F-16C 30s used the smaller intake. The kit does have the small intake used on the F-16As. So I guess since I am doing a plane with year 85 I can use the small P&W intake? I read the large intake was not used untill 86. My plane is an F-16C from the South Dakota Lobos 85-1470. Thanks.

Hope this helps

ALL GE-powered F-16s after 86-0261 (block 30) are big-mouths. 86-0261 and previous GE jets are small-mouths.
