E-85 question

[G-Bodydude1983]

I have been wanting to convert my g body to e-85 for some time now and was wondering if anyone here has experience with converting a Holley 4150 to e-85. I have the appropriate fuel lines and plenty of flow, but do I have to change out metering blocks? The engine is a very mild 350 sbc

Really better off buying metering blocks and or the kit to do it not all that bad too do, but there are write ups online hoping what and were to drill
