Hi Scott:
At again taking a risk at being foolish, you may want to consider the
following: you shouldn't be looking at a standard and working from there. My
guess is that regardless of what the standard flow rate may be rated for
your heads, I think you are looking for a "normalcy" between all eight
chambers, that is, looking for a balanced engine. I take it you may be
looking at pressure levels at each chamber to make a guess at flow rate,
right? Then if this is correct, you may want to achieve the same or near
pressure level/flow rate from each part of the head. If you have some
chamber that gives the lowest pressure (?), normalize the rest of the
chambers for that target level (ie, port the other heads to achieve that
level). Also, check to make sure that no gasket material is in the way of
making a good flow measurement. Thanks. Another .00002/100% thought brought
to you by me. Cal #????
