11-12 heads on a S550 short block?

[weemon2k2]

Has anyone used 2011-2012 cylinder heads on a S550 short block? The 11-12 coyotes used 12mm head bolts, 13-16's used 11mm bolts. I was told my 2011 heads won't work with a S550 block because of this

I thought I saw somewhere they just used the 11mm bolts

the 11-12 heads will work fine

Thanks for the info guys. Didn't want to order a short block only to find out I need new heads too.
So from what I understand, I'll need to use 2015+ head gaskets and head studs to make this work
