860 w/slp twin's need race fuel 8000+ elevation

Will Carls cycle 860 with twins running 8000-10,000 need race fuel?

Thanks,

I just bought the same set up. I assume it's an 860 kit on a carbed 600 block. I have been told to run 80% pump gas and 20% race fuel.

Ya. I was thinking the CFI 860. But I think both require race fuel. SLP Twin pipe setup recommended 20% race fuel and must run above 6000 ft. I was wondering if I could get away with running less race fuel at higher elevations. Say 8000 to 10,000ft with little to no race fuel.
