It's too late now, but the fact of the matter is the the head bolt pinch in is not much of a flow restriction in the E heads in out of the box form.
what is however is the height of the runner from the crown of the short turn on back to the Intake flange.
This is due to how darn deep the valve bowl is in these E heads, and yes even in the 87 CC version.
Only once the roof is raised to what's geometricly needed to match the bowl roof is the removal of the head bolt pinch in worth a good bunch of air flow above .450" lift.
Oh and by the way, I don't think Sam or anyone is going to take kindly to being called a kid as you have done!
