Another "what will it make", but a little different

46* close is trapping A LOT of cyl psi.

Make sure you make very accurate placements of the dowel pin locations, otherwise you will have chambers misplaced over the bores...and end up too big on one side or the other.
And leave the chambers just a c hair smaller, like .010-.015 smaller around.

Also know that in your ragged edge compression will benifit from not having the chambers edge massively overhanging in to cyl which will turn into hot spot for preignition.
