ive read the thread on honda-tech about the d16z6 head over a d15b7 mini swap.

the guy who did it gained about 25hp with stock head i/t,i/m, with all new parts,
and some no name parts

im wondering how much i will gain if i rebuilt my head with new valve stems etc,
edelbrock headers, aem cold air intake, blox intake manifold, 5zigen muffler and all
new parts for the swap.

around how much more estimated hp will i gain? thanks
