Generation IV Internal Engine - LS7 head gasket on 427 LS2?

have a slight dilemma as I ran out of Cometic 4.125" bore head gaskets but need to finish the engine where the starter nose broke off. Does anyone know if I can use a stock LS7 head gasket on a 4.125" bored LS2 block with Darton sleeves (Katech prepped 427 block)?

These I could get quickly from the friendly (gulp) GM dealer here.

I wouldn't see why not? I am even using LS7 gaskets with my 347 & AFR's. The gasket size diameter is 4.150 IIRC...
