D-66 questions
So I ordered myself a digital protractor (which somebody here recommended) and here's what I found. The angle on the D-64 (64-5 heads) is 18 degrees and the angle on the D-66 (66 and up heads) is 10 degrees. so to use early manifold on late heads or late manifold on early heads you need an 8 degree tapered washer (fat side up for one and fat side down for the other and some VERY careful realignment of the bolt holes (which are ovesized for the bolts on every LA manifold). Here are some pictures
