No such thing AFAIK, certainly in regards to G.E. RXs (standard bands are 406-420 & (rare) 420-450). 434 is right in the middle between the low end of 450-470 & 406-420, so probably makes no difference which split you try to bring up or down. Since 88s are much more common, I'd go with that. Using high-side LO will allow the LO chain to easily reach 434 with little if any mods. For optimum RX you will need to modify the front-end helicals. I put a 450-470 Mastr II RX on 422 with no mods at all. It does work & everything tunes up but the sensitivity is about 6 dB off of where it should be, probably due to the front-end helicals being lossier since they're not optimized for that band.
